fix: insert CSI u handler into model.go + add tui tests
The previous commit defined parseCSIuBytes but failed to insert the handler into Update(). Now properly inserted before the textinput fallback. Add 10 test cases for parseCSIuBytes covering ctrl+alt+f/c/ m/p/h, ctrl+shift+c, alt+c, and invalid sequences. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
