Clicking an undownloaded video now plays it in the app instead of
handing off to the browser. YouTube's iframe embed cannot be used —
it rejects a tauri:// origin with Error 153 — so yt-dlp resolves
YouTube's HLS master playlist instead, whose H.264+AAC variants
AVFoundation streams natively in WKWebView, adaptive up to 1080p.
Adds an optional Tiles view alongside the list, remembered between
launches.
The title bar is now transparent with the title hidden, and the app
paints that strip itself in the page background so it matches instead
of showing macOS chrome beside the traffic lights.
ffmpeg only accepts -version (single dash); it exits 8 on --version and
writes to stderr, so the status panel reported it missing even when
installed. Version flags are now per-tool and both streams are read.
The player used max-h-full inside a grid, which a 1080x1920 Short
overflowed. Switched to absolute fill with object-contain so portrait
and landscape both letterbox correctly.
Also sized the window to 1180x780 centered, which fits a laptop display.
Refresh fetches 8 channel feeds concurrently and mirrors thumbnails to
disk so the offline feed still renders. Downloads are capped at 2 and
shell out to yt-dlp with an absolute binary path, since GUI apps do not
inherit a login shell PATH.
