fix: SSE stream endpoint with proper HTTP/2 stream handling and heartbeat
...
- Fixed /api/stream/requests endpoint HTTP/2 INTERNAL_ERROR
- Use reply.raw.writeHead() instead of Fastify headers API for SSE
- Added 30s heartbeat to keep connection alive
- Proper event format with 'event:' and 'data:' fields
- Comprehensive error handling and cleanup on disconnect
- Mirrors working pattern from /api/stream/costs endpoint
- Resolves dashboard perpetual 'Loading...' state

fix: only send HSTS header on HTTPS connections, not HTTP
...
The learning process was failing to communicate with the gateway because:
1. Gateway was sending 'Strict-Transport-Security' header on HTTP responses
2. Node.js fetch respects HSTS and upgrades subsequent requests to HTTPS
3. Gateway only has HTTP listener (localhost:3103), no HTTPS
4. Result: SSL 'packet length too long' error on second request attempt
Solution: Modified registerHSTSMiddleware to only send HSTS header when
the connection is already secure (HTTPS or x-forwarded-proto: https).
HTTP connections will not get the HSTS header, preventing the forced upgrade.

refactor: MAGATAMA pipeline code quality audit — all functions <50 lines
...
Complete code quality audit of llm-gateway pipeline modules for MAGATAMA standard compliance (50-line function maximum). All pipeline functions refactored to ensure high cohesion and readability.
Pipeline module compliance (verified):
✅ llm-client.ts — Refactored callOllama() (58→26 lines) via helper extraction
✅ instrumented-llm-client.ts — All functions <50 lines (wrapper layer)
✅ router.ts — Refactored routeByScore() (81→32 lines) via delegation
✅ request-scorer.ts — 870-line file, all functions <50 lines
✅ external-providers.ts — All functions <50 lines (49-line max)
✅ post-validator.ts — All validators <50 lines
Verified:
✓ npm run build (TypeScript, zero errors)
✓ All 6 pipeline modules independently audited
✓ Production-ready for Erik deployment (PM2 ids 19+20, port 3103)
Deployment target: Gitea (192.168.178.196:3000/rene/llm-gateway)
