- Alt+Backspace for word deletion
- Export Keys constants and helper functions from @mariozechner/pi-tui

- Line-end resets only turn off underline, preserving background colors

fixes#109
Browse previously submitted prompts using Up/Down arrow keys, similar to
shell history and Claude Code's prompt history feature.
- Up arrow when editor is empty: browse to older prompts
- Down arrow when browsing: return to newer prompts or clear editor
- Cursor movement within multi-line history entries supported
- History is session-scoped, stores up to 100 entries
- Consecutive duplicates are not added to history
Includes 15 new tests for history navigation behavior.
- Add Ctrl+W for word deletion (stops at whitespace/punctuation)
- Add Ctrl+U for delete to start of line (merges with previous line at col 0)
- Change Ctrl+K from delete entire line to delete to end of line (merges with next line at EOL)
- Add Option+Backspace support in Ghostty (maps to Ctrl+W via ESC+DEL sequence)
- Cmd+Backspace in Ghostty works as Ctrl+U (terminal sends same control code)
- Update README and CHANGELOG with new keyboard shortcuts
