francylisboacharuto bac2b27bb8 feat: v4.0 Cross-Platform Modernization — Agent Skills Open Standard compliance

BREAKING CHANGES:
- Remove -cskill suffix from all skill names (use standard kebab-case)
- Simplify marketplace.json to only official fields (fixes Issue #5)
- SKILL.md body must be <500 lines (progressive disclosure via references/)

New features:
- Cross-platform support for 8+ platforms (Claude Code, Copilot, Cursor, Windsurf, Cline, Codex CLI, Gemini CLI)
- scripts/install-template.sh: Auto-detect platform installer with --dry-run
- scripts/validate.py: Spec compliance checker for generated skills
- scripts/security_scan.py: Security scanner for hardcoded keys and dangerous patterns
- MIGRATION.md: v3.x to v4.0 migration guide
- 6 new reference files for progressive disclosure from lean SKILL.md

Key changes:
- SKILL.md: 4,116 → 272 lines with spec-compliant YAML frontmatter
- marketplace.json: Stripped to {name, plugins} only
- article-to-prototype-cskill/ → article-to-prototype/
- stock-analyzer-cskill/ → stock-analyzer/
- Export system integrates validation + security scanning
- README.md rewritten for all supported platforms
- Phase 5 pipeline outputs SKILL.md-first, spec-compliant skills

SC-015: Compatibility Field Included When Platform-Specific Features Used

Covers: FR-010 — Generated skills SHOULD include compatibility field when platform-specific features are used Type: Happy Path

Given

The meta-skill is invoked to create a skill that uses platform-specific features
Input: "Create a skill that uses Claude Code's allowed-tools feature to restrict tool access to only Bash and Read"

When

Phase 5 generates the SKILL.md

Then

The SKILL.md frontmatter includes a compatibility field
The compatibility value describes which platforms or features are required (<=500 chars)
The allowed-tools experimental field is also present in frontmatter

Verification Method

Method: Automated test

Steps:

Run the meta-skill with the platform-specific input
Parse the YAML frontmatter
Assert compatibility key is present
Assert len(compatibility) <= 500
Assert the value references the platform-specific constraint

Expected evidence: Frontmatter contains compatibility: "Requires Claude Code for allowed-tools support" (or similar). Length is <=500 chars.
