* run post action cleanup in play script after main completes
* clarify that GITHUB_RUN_ID is the actual bail-out gate in play context
* treat GITHUB_RUN_ID as optional in post cleanup
* replace dynamic import with static import of `runPostCleanup`
Export `runPostCleanup` from post.ts and guard the top-level
execution with `import.meta.url` so it only auto-runs as an
entry point. play.ts now statically imports and calls it.
* move runPostCleanup into finally block and let failures propagate
* refactor post cleanup into utility module
move post cleanup logic into a dedicated utility and keep post.ts as a pure script entrypoint. update play.ts to import the shared utility directly and normalize direct-execution detection.
