v0.7.1

Changed

• Splash Screen Timer — adjusted default splash screen display duration.
• Markdown Rendering — improved header detection and checklist rendering in chat messages.

Fixed

• Side Panel Auto-Expansion — fixed a bug where the left panel would auto-expand when adding attachments, submitting chat messages, or resizing content. The panel width now stays fixed unless manually resized by the user via the drag handle.
• Attachment Filename Overflow — long attachment filenames (e.g., screenshot names) no longer push the panel wider. Filenames are truncated to 20 characters with full name shown on hover tooltip. Multiple attachments wrap to new lines instead of extending horizontally.
• Color Parsing — fixed color parsing to support hex color strings in parse_color_args.
• Zoom Limits — extended from 0.5–1000.0 to 0.1–5000.0 for both mouse and keyboard, so you can zoom much further in/out before hitting limits
