feat(graph): force-directed agent graph visualization with kanban-zone task layout

Force-directed graph visualization for agent teams.

Package: @claude-teams/agent-graph (isolated workspace package)
- Space theme: bloom, particles, hex grid, depth stars
- Members as hexagonal nodes with breathing glow
- Tasks as pill cards in kanban columns (todo/wip/done/review/approved) per owner
- Message particles along edges (real-time only)
- Deterministic layout, Figma-style pan, scroll/pinch zoom
- Clean Architecture: ports/adapters/strategies, ES #private classes

Integration: features/agent-graph/ (adapter + overlay + tab)
- Full-screen overlay (Cmd+Shift+G) + Pin as Tab
- Graph button in Team section header
- Frustum culling, zero per-frame allocations, adaptive fps
- Performance overlay via ?perf query param

Also: CI runs on all PR branches, features/CLAUDE.md architecture guide

+
+### Minimal Feature (no domain layer)
+
+Small features that don't need business logic:
+
+```
+src/renderer/features/<feature-name>/
+  ├── <Feature>Adapter.ts       # Zustand → feature data
+  ├── <Feature>View.tsx         # Main component
+  └── index.ts                  # Public API
+```
+
+### When to Extract a Workspace Package
+
+Some features benefit from a separate `packages/<name>/` workspace package:
+
+| Keep in `features/` | Extract to `packages/` |
+|---------------------|----------------------|
+| Tightly coupled to our UI | Reusable in other projects |
+| Uses our Zustand store | Framework-agnostic (only React peer dep) |
+| Small (<500 LOC) | Large (>1000 LOC of core logic) |
+| No external deps | Has its own dependencies (d3-force, etc.) |
+
+Example: `agent-graph` has BOTH:
+- `packages/agent-graph/` — Canvas rendering, d3-force simulation (reusable, no project coupling)
+- `features/agent-graph/` — Adapter + overlay + tab (thin integration, imports from store)
+
+---
+
+## Real-World Example: agent-graph
+
+```
+features/agent-graph/                    ← Integration layer (3 files)
+  ├── useTeamGraphAdapter.ts             ← Adapter: TeamData → GraphDataPort
+  ├── TeamGraphOverlay.tsx               ← UI: full-screen overlay
+  └── TeamGraphTab.tsx                   ← UI: tab wrapper
+
+packages/agent-graph/                    ← Isolated package (34 files)
+  ├── src/ports/                         ← GraphDataPort, GraphEventPort, types
+  ├── src/canvas/                        ← Canvas 2D renderers
+  ├── src/strategies/                    ← Strategy pattern per node kind
+  ├── src/hooks/                         ← Simulation, camera, interaction
+  └── src/components/                    ← GraphView, GraphCanvas, Controls
+```
+
+The adapter (`useTeamGraphAdapter.ts`) is the **only file** that imports from `@renderer/store`. Everything else depends only on port interfaces.
+
+---
+
+## SOLID Principles
+
+### S — Single Responsibility
+
+Each layer has exactly one reason to change:
+
+| Layer | Changes when... | Does NOT change when... |
+|-------|----------------|------------------------|
+| `ports/` | Feature contract changes | Store structure changes |
+| `adapters/` | Store data model changes | Canvas rendering changes |
+| `domain/` | Business rules change | React version updates |
+| `ui/` | UX/layout changes | Data mapping changes |
+
+### O — Open-Closed
+
+Extend via new classes, never modify existing ones:
+
+```typescript
+// ✅  New node kind = new class, zero changes to existing code
+class ReviewNodeRenderer implements NodeRenderer { ... }
+
+// Register it — the registry and canvas loop don't change
+NodeRendererRegistry.register(new ReviewNodeRenderer());
+```
+
+### L — Liskov Substitution
+
+Any implementation of a port can replace another without breaking the feature:
+
+```typescript
+// Both adapters satisfy GraphDataPort — feature works with either
+class LiveTeamAdapter implements GraphDataPort { ... }   // Real-time Zustand data
+class MockTeamAdapter implements GraphDataPort { ... }   // Static test data
+class ReplayTeamAdapter implements GraphDataPort { ... } // Recorded session playback
+
+// Feature doesn't know or care which one it gets
+const view = <GraphView data={adapter} />;
+```
+
+### I — Interface Segregation
+
+Split ports by consumer. Each consumer depends only on what it needs:
+
+```typescript
+// ✅  Three small ports
+interface GraphDataPort { nodes: GraphNode[]; edges: GraphEdge[]; }
+interface GraphEventPort { onNodeClick?(ref: DomainRef): void; }
+interface GraphConfigPort { bloomIntensity?: number; showTasks?: boolean; }
+
+// ❌  One massive interface — forces every consumer to know about everything
+interface GraphPort {
+  nodes: GraphNode[]; edges: GraphEdge[];
+  onNodeClick?(ref: DomainRef): void;
+  bloomIntensity?: number; showTasks?: boolean;
+}
+```
+
+### D — Dependency Inversion
+
+High-level modules (feature UI) depend on abstractions (ports), not on low-level modules (Zustand store).
+
+```
+UI → depends on → Port interface ← implemented by ← Adapter → depends on → Store
+
+Feature code never touches the store. The adapter translates in both directions.
+```
+
+---
+
+## Class-Based Patterns
+
+Prefer **classes** over functions for domain logic, services, adapters, and stateful code. Use the **latest ECMAScript class features** (ES2024+).
+
+### Modern Class Syntax
+
+```typescript
+class TeamGraphAdapter implements GraphDataPort {
+  // ─── ES private fields (NOT TypeScript `private`) ─────────────
+  readonly #store: StoreApi;
+  #cachedNodes: GraphNode[] = [];
+  #lastTeamName = '';
+
+  // ─── Static factory (prefer for complex initialization) ───────
+  static create(store: StoreApi): TeamGraphAdapter {
+    return new TeamGraphAdapter(store);
+  }
+
+  // ─── Constructor with DI ──────────────────────────────────────
+  constructor(store: StoreApi) {
+    this.#store = store;
+  }
+
+  // ─── Accessors (get/set) ──────────────────────────────────────
+  get nodes(): readonly GraphNode[] {
+    return this.#cachedNodes;
+  }
+
+  // ─── Public method (port contract) ────────────────────────────
+  adapt(teamData: TeamData): GraphDataPort {
+    if (teamData.teamName === this.#lastTeamName) return this;
+    this.#lastTeamName = teamData.teamName;
+    this.#cachedNodes = this.#buildNodes(teamData);
+    return this;
+  }
+
+  // ─── ES private method ────────────────────────────────────────
+  #buildNodes(data: TeamData): GraphNode[] {
+    return data.members.map(m => ({ id: m.name, kind: 'member', ... }));
+  }
+
+  // ─── Disposable (cleanup) ─────────────────────────────────────
+  [Symbol.dispose](): void {
+    this.#cachedNodes = [];
+  }
+}
+```
+
+### Key Rules
+
+| Rule | Do | Don't |
+|------|-----|-------|
+| Private fields | `#field` (ES private) | `private field` (TS keyword) |
+| Private methods | `#method()` | `private method()` |
+| Readonly fields | `readonly #field` | Mutable when immutability intended |
+| Static factory | `static create()` | Complex constructor logic |
+| Disposal | `[Symbol.dispose]()` or `dispose()` | Forgetting cleanup |
+| Type narrowing | `instanceof` checks | `as` casts |
+
+### When to Use Classes vs Functions
+
+| Use Case | Pattern | Why |
+|----------|---------|-----|
+| Domain models with state | **Class** | Encapsulation, lifecycle |
+| Adapters (data mapping) | **Class** with caching | State for memoization |
+| Services (business logic) | **Class** with DI | Testable, injectable |
+| Canvas renderers | **Class** implementing strategy | Polymorphism |
+| React components | **Function component** | React requires it |
+| React hooks | **Function** | React requires it |
+| Pure stateless utilities | **Function** | Simpler, no overhead |
+| Constants | `as const` object | Immutable |
+
+### Dependency Injection
+
+Always inject dependencies through the constructor:
+
+```typescript
+class FeatureService {
+  readonly #data: FeatureDataPort;
+  readonly #events: FeatureEventPort;
+
+  constructor(data: FeatureDataPort, events: FeatureEventPort) {
+    this.#data = data;
+    this.#events = events;
+  }
+
+  execute(): void {
+    const result = this.#data.getNodes();
+    this.#events.onResult?.(result);
+  }
+}
+
+// Wiring in a hook:
+function useFeature(): FeatureService {
+  const adapter = useMemo(() => FeatureAdapter.create(store), [store]);
+  return useMemo(() => new FeatureService(adapter, eventHandler), [adapter]);
+}
+```
+
+### Strategy Pattern
+
+```typescript
+interface NodeRenderer {
+  readonly kind: string;
+  draw(ctx: CanvasRenderingContext2D, node: Node): void;
+  hitTest(node: Node, x: number, y: number): boolean;
+}
+
+class MemberNodeRenderer implements NodeRenderer {
+  readonly kind = 'member';
+  draw(ctx: CanvasRenderingContext2D, node: Node): void { /* ... */ }
+  hitTest(node: Node, x: number, y: number): boolean { /* ... */ }
+}
+
+class NodeRendererRegistry {
+  readonly #renderers = new Map<string, NodeRenderer>();
+
+  register(renderer: NodeRenderer): this {
+    this.#renderers.set(renderer.kind, renderer);
+    return this;
+  }
+
+  get(kind: string): NodeRenderer | undefined {
+    return this.#renderers.get(kind);
+  }
+}
+
+// Usage:
+const registry = new NodeRendererRegistry()
+  .register(new MemberNodeRenderer())
+  .register(new TaskNodeRenderer());
+```
+
+---
+
+## Error Handling
+
+```typescript
+// Domain errors — typed, not string messages
+class FeatureError extends Error {
+  constructor(
+    readonly code: 'INVALID_DATA' | 'RENDER_FAILED' | 'ADAPTER_ERROR',
+    message: string,
+    readonly cause?: unknown,
+  ) {
+    super(message);
+    this.name = 'FeatureError';
+  }
+}
+
+// In adapters — catch and wrap external errors
+class FeatureAdapter {
+  adapt(data: unknown): FeatureDataPort {
+    try {
+      return this.#transform(data);
+    } catch (err) {
+      throw new FeatureError('ADAPTER_ERROR', 'Failed to adapt data', err);
+    }
+  }
+}
+
+// In UI — catch at boundary, show fallback
+function FeatureView({ data }: Props) {
+  // React error boundary or try/catch in event handlers
+  // Never let feature errors crash the host app
+}
+```
+
+---
+
+## Inter-Feature Communication
+
+Features MUST NOT import from each other directly. If two features need to share data:
+
+```
+Feature A  →  emits event  →  Host app (TeamDetailView)  →  passes data  →  Feature B
+```
+
+Pattern: use `CustomEvent` on `window` (same as keyboard shortcuts):
+
+```typescript
+// Feature A fires:
+window.dispatchEvent(new CustomEvent('feature-a:data-ready', { detail: { ... } }));
+
+// Host app listens and passes to Feature B via props/ports
+```
+
+---
+
+## Testing
+
+Tests live in `__tests__/` inside the feature directory.
+
+```typescript
+// __tests__/adapters.test.ts — test data mapping
+describe('FeatureAdapter', () => {
+  it('maps TeamData members to GraphNodes', () => {
+    const adapter = new FeatureAdapter();
+    const result = adapter.adapt(mockTeamData);
+    expect(result.nodes).toHaveLength(3);
+    expect(result.nodes[0].kind).toBe('lead');
+  });
+});
+
+// __tests__/domain.test.ts — test business logic
+describe('SimulationService', () => {
+  it('applies orbit force to task nodes', () => {
+    const service = new SimulationService(mockConfig);
+    service.tick(0.016);
+    expect(service.nodes[0].x).toBeDefined();
+  });
+});
+```
+
+Run: `pnpm test -- --testPathPattern=features/<name>`
+
+---
+
+## Integration with Main App
+
+Features connect through minimal **registration points** in shared files:
+
+### Tab Registration (3 files)
+
+```typescript
+// 1. src/renderer/types/tabs.ts — add to union
+type: '...' | '<feature>';
+
+// 2. src/renderer/components/layout/PaneContent.tsx — add route
+{tab.type === '<feature>' && (
+  <TabUIProvider tabId={tab.id}>
+    <FeatureView ... />
+  </TabUIProvider>
+)}
+
+// 3. src/renderer/components/layout/SortableTab.tsx — add icon
+<feature>: SomeIcon,
+```
+
+### Overlay Registration (1 file)
+
+```typescript
+// In host component (e.g., TeamDetailView.tsx):
+const FeatureOverlay = lazy(() =>
+  import('@renderer/features/<feature>/ui/FeatureOverlay')
+    .then(m => ({ default: m.FeatureOverlay }))
+);
+```
+
+### Keyboard Shortcut (1 file)
+
+```typescript
+// In useKeyboardShortcuts.ts:
+if (key === '<x>' && event.shiftKey && !event.altKey) {
+  window.dispatchEvent(new CustomEvent('toggle-<feature>', { detail }));
+}
+```
+
+---
+
+## Naming Conventions
+
+| Entity | Convention | Example |
+|--------|-----------|---------|
+| Feature directory | `kebab-case` | `agent-graph/` |
+| Port interfaces | `PascalCase` + `Port` suffix | `GraphDataPort` |
+| Domain classes | `PascalCase` | `SimulationService` |
+| Adapter classes | `PascalCase` + `Adapter` suffix | `TeamGraphAdapter` |
+| UI components | `PascalCase` | `GraphView`, `GraphOverlay` |
+| Hooks | `camelCase` + `use` prefix | `useTeamGraphAdapter` |
+| Test files | `<module>.test.ts` | `adapters.test.ts` |
+| Type files | `camelCase` or `types.ts` | `types.ts` |
+| Barrel | `index.ts` | `index.ts` |
+
+---
+
+## Existing Features
+
+| Feature | Path | Companion Package | Description |
+|---------|------|-------------------|-------------|
+| `agent-graph` | `features/agent-graph/` | `packages/agent-graph/` | Force-directed graph visualization |
+
+---
+
+## Anti-Patterns
+
+```typescript
+// ❌  Feature imports from another feature
+import { X } from '@renderer/features/other-feature/X';
+
+// ❌  UI component imports store directly (only adapters may)
+import { useStore } from '@renderer/store';
+
+// ❌  Feature imports from @renderer/components/*
+import { KanbanBoard } from '@renderer/components/team/kanban/KanbanBoard';
+
+// ❌  TypeScript `private` instead of ES #private
+class Bad { private field = 1; }  // Use: #field = 1;
+
+// ❌  Mutable global state
+let globalCache = {};
+
+// ❌  `any` or `as any`
+const data = response as any;
+
+// ❌  God-class with mixed responsibilities
+class FeatureManager {
+  fetchData() { ... }
+  renderUI() { ... }
+  handleClick() { ... }
+  saveToStorage() { ... }
+}
+```
