feat(FN-1514): add regression tests for skillSelection across executor, step-session, and triage

Browse Source 
- Add executor skillSelection regression tests covering model override resolution
- Add step-session skillSelection tests for per-step agent creation
- Add triage skillSelection tests for spec generation with projectRootDir
- Verify skillSelection context propagation across all execution paths
