* fix(scripts): bound duplicate PR closure GitHub lookups
The duplicate PR closure helper performs multiple sequential gh API
reads and writes after a merge. Each call used execFileSync without a
timeout, so one stalled GitHub request could block the surrounding
workflow job until it expires.
Add a 60-second timeout and SIGKILL to the default gh runner, applied
to both read-only lookups and pr edit writes that forward stdin.
* test(scripts): add real behavior proof for duplicate PR closure timeout
Add two live subprocess tests using the real spawnSync (not mocked) to
prove the timeout + SIGKILL surface works against actual child
processes:
- A 1 ms timeout against a long-running node subprocess proves
SIGKILL is delivered and the timeout triggers correctly.
- A fast node -e 0 subprocess with the production 60-second bound
proves the timeout does not false-positive on healthy completions.
Switch the vi.mock to a partial mock using importOriginal so
spawnSync remains the real implementation for live tests while
execFileSync stays mocked for the DI-based option assertions.
* refactor(scripts): inject duplicate closure GitHub runner
* fix(scripts): declare trusted tooling pin validator
