fix: stabilize PR comment sessions

[DjDeveloperr]

Summary

• Preserve the native daemon recoverable-restart contract in the npm CLI wrapper for simdeck daemon run.
• Keep daemon metadata pointed at the stable wrapper process via SIMDECK_DAEMON_METADATA_PID, so PR-session lifecycle checks watch the right PID.
• Keep iOS and Android PR-comment workflows tolerant of the short health gap during a legitimate daemon restart.
• Fix artifact lookup and status comments so missing/expired artifacts produce an explicit startup failure instead of an immediate misleading ended status.

Root cause

The PR-comment workflows install SimDeck from npm, where simdeck is bin/simdeck.mjs. The native daemon already exits with code 75 for recoverable restarts, but the npm wrapper passed that exit through. The workflow then treated the wrapper PID as dead even though daemon metadata could still point at a separate native process.

Testing

• npm run test:github-actions
• npx prettier --check bin/simdeck.mjs actions/run-ios-comment-session/action.yml actions/run-android-comment-session/action.yml scripts/github-actions.test.mjs
• git diff --check
