fix: address PR review feedback for auto-update

- Register manual check listeners before checkForUpdates() to avoid race
- Strip prerelease/build metadata in version comparison
- Add res.setEncoding("utf8") for GitHub API response
- Stream file hashing in CI script instead of reading into memory
- Add directory existence checks in fix-latest-yml.mjs
- Define UpdateStatus type locally in preload to avoid tsconfig scope issues
- Show error dialog for manual check failures (parse/network errors)
