docs: synchronize implementation documentation with codebase (2025-12-31)

Update all base directory documentation to accurately reflect current codebase state:

- IMPLEMENTATION_PLAN.md: Correct CI/CD status (operational), update test counts (75 actual),
  clarify week completion status (1-2 + partial 5 complete)
- IMPLEMENTATION_STATUS.md: Add verification dates, detailed test breakdowns, updated remaining
  work estimates, recent improvements section
- STATUS.md: Update from 35 to 75 tests, add integration test details, include lib/ modules
- PHASE1_COMPLETION.md & PHASE2_COMPLETION.md: Add historical milestone notes

Key corrections:
- CI/CD pipeline IS operational (.github/workflows/test.yml)
- install.sh DOES copy lib/ directory (verified lines 78, 91, 148)
- 75 tests accurately reported (15 rate + 20 exit + 20 loop + 20 edge)
- Week 5 partially complete (edge cases done, features not implemented)
- Weeks 3-4 and 6 not started (accurate status vs. optimistic claims)

All documentation now synchronized with codebase as of 2025-12-31.
