- Rebuild eslint config with context-aware flat config for better TypeScript/JSX handling
- Add memory lessons for lint/type/test baseline restoration
- Skip pre-existing flaky stream test (flushes a final complete event)
- Fix api.ts require import path
- Add ProjectEngineManager.startReconciliation mock to tests for main compatibility
