fix: resolve all 14 test failures to 0

- Remove duplicate notifyAutomationStateChanged that shadowed real impl (sessionState 3→0)
- Fix messages.ts stub: re-export instead of type-only (ExecuteTool/VaultHttpFetch mock leaks)
- Fix CWD-dependent paths in queryModelOpenAI and VaultHttpFetch tests (use import.meta.url)
- Add missing logger.ts stub for remote-control-server
- CI: add --isolate flag, baseline 14→0
- Tests: 3643 pass,14 fail → 3857 pass,0 fail (--isolate)
