test(chat_composer): Add comprehensive test suite
Add 23 tests covering ChatComposer functionality: - Basic operations: creation, char insertion, backspace, delete - Submit and cancel actions - Multiline input with Shift+Enter - Cursor movement (left/right, home/end) - Command history navigation (up/down arrows) - Command mode (/ prefix) - Ctrl key shortcuts (u=clear, k=kill, w=delete word) - Unicode character support - Placeholder and max_history configuration - Focus state management 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
