Add ability to minimize Hikari to the system tray when closing the window
instead of fully exiting. When enabled, clicking the close button hides
the window and shows a tray icon with "Show Hikari" and "Quit" options.
- Add tray module with system tray setup and menu handling
- Add minimize_to_tray config option in settings
- Handle window close event to hide instead of close when enabled
- Add tray icon click handler to restore window
## Summary
- Adds Tauri clipboard-manager plugin to read images from native clipboard
- Falls back to native clipboard when WebView clipboard API returns empty (fixes screenshot paste)
- Allows sending messages with just attachments (no text required)
- Logs attached files to output with 📎 emoji
## Test plan
- [ ] Build and run the app natively on Windows
- [ ] Copy a screenshot (Win+Shift+S) and paste in the chat input
- [ ] Verify the screenshot appears as an attachment preview
- [ ] Send the attachment and verify Claude receives the file path
- [ ] Test sending a message with only an attachment (no text)
- [ ] Verify the 📎 log line shows the attached filename
**Note:** Paste will not work in WSLg dev environment due to clipboard isolation - needs native Windows build to test.
