gsxdsm 0fbeba50d1 FN-8937: rescue project engine test quarantine

Rescue the project engine suite by making subprocess watchdog behavior deterministic.

- Capture real timer APIs for subprocess watchdogs and isolate failure ownership.
- Mock integration-branch resolution to prevent host git during lifecycle tests.
- Add watchdog regression coverage and remove the expired quarantine exclusion.
