fix(ci): fix AppImage validation, macOS runner, and script permissions

- Fix AppStream metadata: add <launchable>, <developer>, <content_rating>,
  and <releases> elements; rename to com.rgitui.app.metainfo.xml to match
  the component ID and resolve the filename-cid-mismatch warning.
- Use macos-14 for aarch64-only macOS builds (macos-13 unavailable,
  macos-latest cannot cross-compile OpenSSL for x86_64).
- Update README installation table to reflect aarch64-only macOS DMG.
