- New `make release` target generates Pommedoro.dmg.sha256 alongside the DMG
- AutoUpdater.swift checks the remote SHA256 against the local stamp on launch
and prompts the user to update when a mismatch is detected
- install.command stamps the SHA256 of the source DMG at install time
- "Check for Updates…" menu item (Cmd+U) for manual checks
- Fix break screen close buttons to resume instead of showing work log
- Migrate worklog.log storage to ~/Library/Application Support/Pommedoro/
