fix: improve VCR configuration and skip local service tests in CI

- Update VCR config to exclude body matching for more reliable cassette playback
- Add pytest marker for tests requiring local services (Ollama, etc)
- Configure CI to skip tests marked as requiring local services
- Re-record async tool test cassettes with telemetry calls only
