feat: Complete v1.1.1 Phases 2 & 3 - Enhancements and Polish

Browse Source 
Phase 2 - Enhancements:
- Add performance monitoring infrastructure with MetricsBuffer
- Implement three-tier health checks (/health, /health?detailed, /admin/health)
- Enhance search with FTS5 fallback and XSS-safe highlighting
- Add Unicode slug generation with timestamp fallback
- Expose database pool statistics via /admin/metrics
- Create missing error templates (400, 401, 403, 405, 503)

Phase 3 - Polish:
- Implement RSS streaming optimization (memory O(n) → O(1))
- Add admin metrics dashboard with htmx and Chart.js
- Fix flaky migration race condition tests
- Create comprehensive operational documentation
- Add upgrade guide and troubleshooting guide

Testing: 632 tests passing, zero flaky tests
Documentation: Complete operational guides
Security: All security reviews passed
