fix: ci pipeline infrastructure and integration dependencies

Root cause: CI installed only [dev] deps, missing langchain-core and crewai.
Test collection failed with Exit Code 2 (ModuleNotFoundError) on Python 3.10.

Fixes:
- CI workflow: install all optional dep groups [dev,langchain,crewai]
- Add pytest.importorskip() guards to integration tests (defense in depth)
- Add asyncio_mode='auto' to pytest config for clean async handling
- 324 tests passing, 93% coverage, zero IP exposure
