Introduce built-in launchd management to remove shell-wrapper indirection and make macOS autostart reliable. - Add `install-launchagent` and `uninstall-launchagent` CLI subcommands. - Create launchd helper module to: - write `~/Library/LaunchAgents/<label>.plist` - invoke app via `sys.executable -m mpd_now_playable.cli` (absolute interpreter path) - set `RunAtLoad`, `KeepAlive` - run `launchctl bootout/bootstrap/kickstart` for install and `bootout` for uninstall - support `--label` and `--force` - Add tests for subcommand dispatch, plist generation, and launchctl flow. - Document the new launchd workflow in README. - Run markdownlint This keeps the setup DRY/KISS, avoids PATH/shell expansion pitfalls in launchd, and gives users a supported and easy autostart path out of the box.
