feat(launcher): Linux play wrapper, patch UX, Gitea sync cleanup

- Play on Linux: use launch.linux_wrapper (wine) or linux_steam_uri; chmod .exe after install
- Windows: retry EBUSY on MPQ replace; download to .new before rename
- After successful sync: remove .bak-* backups; realmlist only Data/enUS (ignore enGB)
- Gitea/distro merge: skip Fractured-Launcher* from GitHub assets (CI default-branch build wins)
- Omit blockmap and builder-debug from staged artifacts and Gitea uploads; upload script validates before clearing attachments
- README and launcher version 1.0.12
