Major updates: adds a libtorrent-based streaming service and refactors UI/behaviour.
Key changes:
- Add streaming service (src/kadr/services/streamer.py): HTTP server + sequential download streamer using libtorrent, StreamLog, buffering/ready states and local streaming URL.
- Rework Detail view (src/kadr/views/detail.py): new hero/backdrop layout, poster sizing, metadata chips, tagline, overview, cast placeholder and a "Watch" action that navigates to a Torrents view; loads full TMDB details/credits asynchronously.
- UI styling (src/kadr/data/style.css): many new classes for detail/hero/cast styling.
- Downloads manager improvements (src/kadr/services/downloads.py): temp dir for torrents, cleanup of stale files, history size cap, unified client launch with error handling.
- TMDB client refactor (src/kadr/services/tmdb.py): unified _fetch helper, added movie_credits/tv_credits endpoints.
- Utils improvements (src/kadr/utils.py): thread-safe LRU image cache, image download concurrency, and slight clipboard command ordering tweak.
- Jackett servers list updated (src/kadr/services/jackett.py): reorder/add servers.
- Project metadata & licensing: switch LICENSE to GPL-3.0-or-later, update pyproject.toml and application about dialog to GPL, adjust package/version in pyproject and __init__.
- README revamped (README.md): reorganized, added badges, Russian text, install/usage sections.
- Added new view/widget files (player/torrents/mpv_widget) and other UI tweaks across widgets/window.
These changes add streaming playback capability, tighten resource handling, and refresh the detail UI while changing the project license to GPL-3.0-or-later.
