8fbdcb6e6f feat: Complete Phase 2.4 - HTTP Content Negotiation 
Implements HTTP content negotiation for feed format selection.

Phase 2.4 Deliverables:
- Content negotiation via Accept header parsing
- Quality factor support (q= parameter)
- 5 feed endpoints with format routing
- 406 Not Acceptable responses with helpful errors
- Comprehensive test coverage (63 tests)

Endpoints:
- /feed - Content negotiation based on Accept header
- /feed.rss - Explicit RSS 2.0
- /feed.atom - Explicit ATOM 1.0
- /feed.json - Explicit JSON Feed 1.1
- /feed.xml - Backward compatibility (→ RSS)

MIME Type Mapping:
- application/rss+xml → RSS 2.0
- application/atom+xml → ATOM 1.0
- application/feed+json or application/json → JSON Feed 1.1
- */* → RSS 2.0 (default)

Implementation:
- Simple quality factor parsing (StarPunk philosophy)
- Not full RFC 7231 compliance (minimal approach)
- Reuses existing feed generators
- No breaking changes

Quality Metrics:
- 132/132 tests passing (100%)
- Zero breaking changes
- Full backward compatibility
- Standards compliant negotiation

59e9d402c6 feat: Implement Phase 2 Feed Formats - ATOM, JSON Feed, RSS fix (Phases 2.0-2.3) 
This commit implements the first three phases of v1.1.2 Phase 2 Feed Formats,
adding ATOM 1.0 and JSON Feed 1.1 support alongside the existing RSS feed.

CRITICAL BUG FIX:
- Fixed RSS streaming feed ordering (was showing oldest-first instead of newest-first)
- Streaming RSS removed incorrect reversed() call at line 198
- Feedgen RSS kept correct reversed() to compensate for library behavior

NEW FEATURES:
- ATOM 1.0 feed generation (RFC 4287 compliant)
  - Proper XML namespacing and RFC 3339 dates
  - Streaming and non-streaming methods
  - 11 comprehensive tests

- JSON Feed 1.1 generation (JSON Feed spec compliant)
  - RFC 3339 dates and UTF-8 JSON output
  - Custom _starpunk extension with permalink_path and word_count
  - 13 comprehensive tests

REFACTORING:
- Restructured feed code into starpunk/feeds/ module
  - feeds/rss.py - RSS 2.0 (moved from feed.py)
  - feeds/atom.py - ATOM 1.0 (new)
  - feeds/json_feed.py - JSON Feed 1.1 (new)
- Backward compatible feed.py shim for existing imports
- Business metrics integrated into all feed generators

TESTING:
- Created shared test helper tests/helpers/feed_ordering.py
- Helper validates newest-first ordering across all formats
- 48 total feed tests, all passing
  - RSS: 24 tests
  - ATOM: 11 tests
  - JSON Feed: 13 tests

FILES CHANGED:
- Modified: starpunk/feed.py (now compatibility shim)
- New: starpunk/feeds/ module with rss.py, atom.py, json_feed.py
- New: tests/helpers/feed_ordering.py (shared test helper)
- New: tests/test_feeds_atom.py, tests/test_feeds_json.py
- Modified: CHANGELOG.md (Phase 2 entries)
- New: docs/reports/2025-11-26-v1.1.2-phase2-feed-formats-partial.md

NEXT STEPS:
Phase 2.4 (Content Negotiation) pending - will add /feed endpoint with
Accept header negotiation and explicit format endpoints.

b0230b1233 feat: Complete v1.1.2 Phase 1 - Metrics Instrumentation 
Implements the metrics instrumentation framework that was missing from v1.1.1.
The monitoring framework existed but was never actually used to collect metrics.

Phase 1 Deliverables:
- Database operation monitoring with query timing and slow query detection
- HTTP request/response metrics with request IDs for all requests
- Memory monitoring via daemon thread with configurable intervals
- Business metrics framework for notes, feeds, and cache operations
- Configuration management with environment variable support

Implementation Details:
- MonitoredConnection wrapper at pool level for transparent DB monitoring
- Flask middleware hooks for HTTP metrics collection
- Background daemon thread for memory statistics (skipped in test mode)
- Simple business metric helpers for integration in Phase 2
- Comprehensive test suite with 28/28 tests passing

Quality Metrics:
- 100% test pass rate (28/28 tests)
- Zero architectural deviations from specifications
- <1% performance overhead achieved
- Production-ready with minimal memory impact (~2MB)

Architect Review: APPROVED with excellent marks

Documentation:
- Implementation report: docs/reports/v1.1.2-phase1-metrics-implementation.md
- Architect review: docs/reviews/2025-11-26-v1.1.2-phase1-review.md
- Updated CHANGELOG.md with Phase 1 additions
