Update Visage to v2.4.1

[cc1234475]

What's new in v2.4.1

Bug fix release for whole scene scanning.

Scene scan no longer fails with a play() AbortError

Some users saw Scene scan failed: The play() request was interrupted because the media was removed from the document. when a scene had no sprite sheet and the scan fell back to the preview video.

The frame extractor called play() on an off-screen video before seeking. That promise can be rejected for reasons outside the plugin's control, and the rejection killed the whole scan. Seeking a preload="auto" video already decodes and presents the frame, so playback was never needed. The call is gone.

Frame extraction hardening

• Seek waits time out after 10s. Before, a stalled decode left the scan spinning forever with no way out except a page reload.
• A stalled or failed seek now keeps the frames already captured and identifies on those, instead of failing the scan.
• Previews reporting a non-finite duration are rejected with a clear message. ffmpeg previews can report Infinity, which produced NaN seek times.
• The video element and both canvases are released in a finally block, so failed scans no longer leak the element and its buffered data.

Verified

Local Stash instance, Chrome: 12 distinct frames extracted in 235ms with zero play() calls, both the sprite and the preview scan paths complete end to end, and load failures surface a plain message with no unhandled rejections.
