- Added cleanup logic so abort/cancel/error paths release locks and emit AbortError consistently.
- Updated related tests to verify source-stream cancellation and handoff escape-handler behavior.
- Updated the catalog changelog by removing a duplicate `Fixed` heading and leaving the NVIDIA Qwen fix in the current release notes.
