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.
