perf: offload heavy I/O to worker thread, reduce renderer re-renders
Main process — worker thread for team data:
- New team-data-worker thread handles getTeamData and findLogsForTask,
  isolating heavy file I/O (scanning 300+ subagent JSONL files) from
  Electron's main event loop. getTeamData dropped from ~2000ms on the
  main thread to ~110ms via the worker.
- Worker-side dedup and 10s result cache for findLogsForTask prevents
  redundant scans when the same task is queried multiple times.
- Discovery cache TTL raised from 5s to 30s — avoids re-scanning the
  entire project directory on every call.
- Message cap at 200 in TeamDataService to keep IPC payloads under 1MB
  (was sending 2200+ messages / ~3MB, stalling Chromium IPC serialization).
- IPC handlers fall back to main-thread execution if the worker is
  unavailable (graceful degradation).

Renderer — useShallow and memoization (55 files):
- Added useShallow to store selectors across 55 renderer files. Batched
  individual useStore() calls (e.g. 17 calls in ExtensionStoreView,
  10 in ConnectionSection) into single useShallow selectors, cutting
  unnecessary re-render checks on every store update.
- MemberLogsTab: three 5-second polling intervals now pause when the
  parent tab is hidden (display:none). Previously 5 hidden tabs × 3
  intervals = 15 polling timers firing continuously.
- KanbanColumn wrapped in React.memo to skip re-renders when props
  haven't changed.
- MemberList: memoized activeMembers/removedMembers/colorMap; replaced
  O(n×m) per-member task scan with a pre-computed reviewer map.
- Bounded timer Maps in store initialization to prevent unbounded growth
  of debounce/throttle tracking maps during long sessions.
