Drag-and-Drop on Main Menu:
- Implemented position-based drop detection on main menu module tiles
- Added detectModuleTileAtPosition() to calculate which tile receives the drop
- Modified window drop handler to pass position and route to appropriate module
- Bypasses Fyne's drop event hierarchy limitation where window-level handlers
intercept drops before widgets can receive them
- Only enabled tiles (currently Convert) respond to drops
- Loads video and switches to module automatically
Cover Art Embedding Fixes:
- Fixed FFmpeg exit code 234 error when embedding cover art
- Added explicit PNG codec specification for cover art streams
- Snippet generation: Added `-c✌️1 png` after mapping cover art stream
- Full conversion: Added `-c✌️1 png` for proper MP4 thumbnail encoding
- MP4 containers require attached pictures to be PNG or MJPEG encoded
Embedded Cover Art Extraction:
- Added EmbeddedCoverArt field to videoSource struct
- Extended ffprobe parsing to detect attached_pic disposition
- Automatically extracts embedded thumbnails when loading videos
- Extracted cover art displays in metadata section (168x168)
- Enables round-trip workflow: generate snippet with thumbnail, load snippet
and see the embedded thumbnail displayed
Technical Details:
- Modified handleDrop to accept position parameter
- Added Index and Disposition fields to ffprobe stream parsing
- Cover art streams now excluded from main video stream detection
- Grid layout: 3 columns, ~302px per column, ~122px per row, starts at y=100
- Embedded thumbnails extracted to /tmp/videotools-embedded-cover-*.png
