Fixed
- Improve large branch diff performance by capping huge inline diff previews, compacting diff tree paths, and allowing horizontal scrolling for long file names.
- Reflow existing long chat sessions after they load so transcripts lay out at the correct width without needing to resize the tool window.
- Keep the prompt send/stop button synchronized when attachments are added, removed, or cleared while a session is busy.
- Reduce transcript restyling work during streaming so large sessions remain responsive.
- Hide expanded diff folder badges and refresh diff tree layout correctly when folders are toggled.
