- Create `unshackle/core/providers/` package with abstract base class, IMDBApi (free, no key), SIMKL, and TMDB provider implementations
- Add consensus-based ID enrichment: cross-references IMDB IDs with TMDB and SIMKL, drops all data from providers that disagree on tmdb_id (likely resolved to wrong title)
- Cache enriched IDs alongside raw provider data so they survive cache round-trips
- Genericize TitleCacher with `cache_provider()`/`get_cached_provider()` replacing provider-specific methods; respect `--no-cache` flag
- Add `--imdb` CLI flag to dl command for direct IMDB ID lookup
Add TrackRequest dataclass to Service base class that centralizes CLI vcodec/range/best_available params. Services read from self.track_request instead of accessing ctx.parent.params directly.
- Add TrackRequest dataclass with codecs, ranges, best_available fields
- Set self.track_request in Service.__init__() from CLI params
- Add _get_tracks_for_variants() helper for per-codec/range API calls
- Update dl.py to detect migrated vs legacy services automatically
- Handle HYBRID+other ranges (e.g. -r HYBRID,SDR) correctly in dl.py
- Support --best-available with multi-range/codec (skip unavailable)
- Add a small helper to move N_m3u8DL-RE final outputs into the expected temp path (preserve actual suffix) and keep subtitle codec consistent with the produced file.
- Skip generic HLS segment merging when N_m3u8DL-RE is in use to avoid mixing in sidecar files and reduce Windows file-lock issues.
- Harden segmented WebVTT merging to avoid IndexError when caption segment indexes exceed the provided duration list.
- Update IMDB tags to use ID only (tt123456) instead of URLs
- Update TMDB tags to use prefix/id format (movie/123456, tv/123456)
- Update TVDB tags to use numeric ID only
- Add XML escaping for tag values
- Fix XML declaration to use double quotes
Fixes#15
* Introduced `MKVToolNix` and `mkvpropedit` binaries to the project.
* Updated the environment check to include required status for dependencies.
* Enhanced the `Tracks` class to raise an error if `MKVToolNix` is not found.
* Modified the `_apply_tags` function to utilize the `mkvpropedit` binary from the binaries module.
* Introduced `SubtitleCodecChoice` to allow selection of subtitle codecs with support for enum names, values, and common aliases.
* Updated `--sub-format` option in `dl.py` to utilize the new `SubtitleCodecChoice`.
