feat: inject bundled mpv plugin for managed launches, remove legacy glob

- SubMiner-managed launcher and Windows shortcut launches inject the bundled plugin when no global plugin is detected
- First-run setup detects and removes legacy global plugin files via OS trash before managed playback starts
- Makefile `install-plugin` target and Windows config-rewrite script removed; Linux/macOS install now copies plugin to app data dir
- AniList stats search and post-watch tracking now go through the shared rate limiter
- Stats cover-art lookup reuses cached AniList data before issuing a new request
- Closing mpv in a launcher-managed session now terminates the background Electron app
