feat: Phase 4 teardown — remove Go codecontext sidecar from deployment

- Remove codecontext service block from docker-compose.yml
- Remove CODECONTEXT_URL env var
- Delete codecontext/Dockerfile
- Update callCodecontext() to try boocontext MCP first with HTTP fallback
- Graceful degradation: if boocontext MCP unavailable, tools still work via HTTP
