fix(tui): handle emoji deletion and cursor movement correctly

Browse source 
Backspace, Delete, and arrow keys now use Intl.Segmenter to operate
on grapheme clusters instead of individual UTF-16 code units. This
fixes deletion of emojis and other multi-codepoint characters.

- **Kitty keyboard protocol on Linux**: Fixed keyboard input not working in Ghostty on Linux when Num Lock is enabled. The Kitty protocol includes Caps Lock and Num Lock state in modifier values, which broke key detection. Now correctly masks out lock key bits when matching keyboard shortcuts. ([#243](https://github.com/badlogic/pi-mono/issues/243))
- **Emoji deletion and cursor movement**: Backspace, Delete, and arrow keys now correctly handle multi-codepoint characters like emojis. Previously, deleting an emoji would leave partial bytes, corrupting the editor state. ([#240](https://github.com/badlogic/pi-mono/issues/240))
