## Summary
- Problem: The `git fetch` in `macos-release.yml` had no timeout bound, risking indefinite CI hangs on network stalls. Same pattern already fixed for Mantis Crabbox workflows in #108940.
- Solution: Add `timeout --signal=TERM --kill-after=10s 120s` before the `git fetch` command.
- What changed: Wrapped the `git fetch --no-tags origin` command with timeout.
- What did NOT change: All release logic remains unchanged.
## Real behavior proof
- **Behavior addressed:** CI macos-release could hang during git fetch.
- **Evidence:** Same timeout pattern as merged Crabbox fix (#108940 / 16c2bbb).
- **Change:** `timeout --signal=TERM --kill-after=10s 120s git fetch --no-tags origin` replaces `git fetch --no-tags origin`.
## Root Cause
- The git fetch was added before the timeout-bounding pattern was standardized across CI workflows.
