Subject: [PATCH] feat(chat): redesign attachments with ContentBlock format and
 file downloads (#397)

- Redesign attachment handling using Anthropic-style ContentBlock array format
  with discriminated unions (text, image, file types)
- Add frontend file download functionality supporting both ContentBlock
  and Markdown formats with authentication tokens
- Fix multi-process conflict causing SQLite database resets by eliminating
  redundant nodemon instances
- Update chat store to build ContentBlock arrays from attachments
- Improve image handling with base64 conversion for upstream API
