feat(docs): complete P2.6 type safety cleanup and P2.7 system invariants
P2.6: Type Safety Cleanup - Replaced 'any' return types in vite-plugin.ts with concrete types (UserConfig, transform return type) - Documented TypeScript mixin 'any[]' exception in PlatformServiceMixin.ts - Audit confirmed: zero 'any' in codebase except documented TS mixin limitation - All external boundaries use 'unknown', all data payloads use 'Record<string, unknown>' P2.7: System Invariants Documentation - Created SYSTEM_INVARIANTS.md documenting all 6 enforced invariants - Added to docs/00-INDEX.md under Policy & Contracts section - Each invariant includes: What, Why, How, Where Progress Docs Updates: - Updated 00-STATUS.md: marked P2.6/P2.7 complete, added type safety invariant note - Updated 01-CHANGELOG-WORK.md: added 2025-12-22 entries for P2.6/P2.7 - Updated 03-TEST-RUNS.md: added P2.6 type safety audit test run - Updated P2-DESIGN.md: marked P2.6 acceptance criteria complete - Updated SYSTEM_INVARIANTS.md: added Type Safety Notes section Baseline Tag: - Created v1.0.11-p0-p1.4-p1.5-p2.6-p2.7-complete TypeScript compilation: ✅ PASSES Build: ✅ PASSES CI: ✅ All checks pass
