chore: remove internal planning and implementation documentation\n\nRemoved internal-only docs:\n- REPO_CLEANUP_PLAN.md (cleanup plan served its purpose)\n- PHASE1_AUTOMATED_REPORT.md, PHASE1_VALIDATION_PLAN.md (internal testing)\n- MULTI_FAUCET_IMPLEMENTATION.md, MODERNIZATION_SUMMARY.md (internal summaries)\n- FINAL_BUG_FIX_SUMMARY.md (internal progress tracking)\n- RELEASE_STRATEGY_SUMMARY.md, SOCIAL_MEDIA_ANNOUNCEMENT_KIT.md (internal marketing)\n- COMMIT_QUICK_REFERENCE.md, COMPREHENSIVE_TODO_LIST.md, GIT_COMMIT_GUIDE.md (dev helpers)\n\nUpdated .gitignore to prevent reintroduction.\n\nResult: Public repo now contains only essential user/developer documentation.
