Adds Library file cleanup alongside chat bulk deletion.
- Preview Library files in a responsive thumbnail grid.
- Search by filename and select individual files or all matching results.
- Delete selected files in batches, with mandatory confirmation.
- Automatically sync Library when opening Library mode or refreshing the page.
- Display files progressively as syncing completes.
- Keep Library metadata and previews in tab memory without persistent extension-managed caching.
- Include account-switch protection and rate-limit handling.
Deleting chats does not automatically delete Library files. Use Library mode to manage those separately.

Version 1.1.1 improves reliability and clarity for large ChatGPT conversation libraries.

• Full sync now handles temporary network and server timeouts with bounded retries.
• Interrupted syncs preserve the previous complete cache and can be retried safely.
• Bulk deletes are paced to reduce ChatGPT rate limiting.
• Delete batches pause safely on rate limits, expired sessions, or request timeouts while keeping unprocessed chats selected.
• The selection control now clearly reads “Show/Hide sidebar checkboxes.”
• Added guidance when the ChatGPT sidebar is closed.

No new permissions or data collection were added.
