add tag-album and clean-playlist-files tasks, script step support, stop fix, rename fix
- New tag-album task: renames tracks to NNN format, sets ID3 tags via mutagen
- New clean-playlist-files task: deletes .cue, .m3u, .nfo and similar junk files
- Pipeline executor now supports script-mode steps (runs directly, no agent)
- Build discography pipeline: convert-audio → clean-playlist-files → prepare → fetch → tag
- Fix stop button: abort signal now kills running agent processes
- Fix job manager: broadcast stopped/error events to WebSocket viewers
- Fix file browser rename: delay focus to avoid context menu close race, left-align input
