🖼️ File Preview UI (New!)
When Claude reads a file, you now get a visual preview widget right in Claude Desktop — no more staring at raw text dumps in the chat.
- Rendered markdown with clean, Medium-inspired typography
- Image preview — PNG, JPEG, GIF, WebP files render inline
- "Load more lines" — expand before/after to see more of the file without re-reading
- Breadcrumb path with an "Open in folder" button to jump straight to the file in Finder/Explorer
- Works on macOS and Windows (hardened Windows path handling to prevent injection)
🔧 Fixes & Improvements
- Build fix:
blocking-offline-update.jsnow correctly copied to dist during build (#329) - Tilde expansion: Restricted
