Pasting a link used to block on a slow yt-dlp metadata lookup (seconds, sometimes 20s+) behind a spinner. Now: - Quality boxes appear instantly with a common set (Best/1080p/720p/480p); the real lookup runs in the background and refines the boxes to the video's actual resolutions (with a subtle 'Checking exact qualities…' indicator). Image posts switch to the image flow when detected. - Lookups are cached per URL, so re-pasting the same link is instant. - Downloads use --concurrent-fragments 4 for parallel fragment fetching. - Paste debounce trimmed 300ms -> 150ms.

The problem
Pasting a link showed a spinner while the app did a slow yt-dlp metadata lookup before revealing the quality boxes — typically a few seconds, and measured at ~22s on a throttled test. That wait reads as "buffering" and hurts the experience.
The fix (perceived + real speed)
--concurrent-fragments 4fetches the video in parallel pieces (throughput boost on YouTube/HLS/DASH).Net effect: the app feels instant even when the network/site is slow, without losing the "show the video's real resolutions" behavior.
