Update REFDB_FORMAT.txt with all work since Nov 20th, delete random docs

DOCUMENTATION FIXES: 1. Updated REFDB_FORMAT.txt (THE developer documentation file): - Added [UPDATE_2025_12_02_PHP_OPTIMIZER] section - Documented all 4 new components (2,960 lines, 45 functions) - Complete workflow documentation for Option 4 - Metrics tracked, safety features, testing status - Future enhancements and git commit history - Added [UPDATE_2025_12_03_DOCUMENTATION] section - Established documentation policies - Established git commit policies (NO AI markers) - Clarified REFDB_FORMAT.txt is primary dev docs 2. Deleted docs/DEVELOPMENT_LOG.md (mistake - random file) ESTABLISHED POLICIES: - REFDB_FORMAT.txt = Developer documentation (update after EVERY change) - README.md = User documentation - NO random .md files in docs/ - NO AI attribution in commits - Update REFDB_FORMAT.txt after every significant change
