Summary

• Remove matches older than the existing 12-hour lifetime immediately while restoring saved state at server startup.
• Share the same expiry logic with periodic cleanup, including safe handling of invalid/missing timestamps.
• Persist the cleaned snapshot before the server begins handling requests.
• Add an integration test that ages a saved match, restarts the server, and confirms the match is gone from both the API and private snapshot.

CI

• Expanded the workflow's pull-request target filters to include feature/multiplayer-persistence.
• Added a push trigger for updates to that persistence branch so its checks can run as the stack evolves.
• The GitHub connector did not return a workflow run for this head when checked, so the new test is not yet verified as passing. Please check the Actions tab for the run before merging.
