Add interactive TUI menu support, terminal helpers, and tests

[joejollands]

Motivation

• Provide basic TUI building blocks (raw-mode input, key parsing, cursor/screen control) to enable interactive menus and embedded inputs.
• Prevent leaving the terminal in an unusable state by adding safe raw-mode enable/restore patterns and cursor hide/show helpers.
• Offer a simple, composable API for single-select menus, checkboxes, and radio lists that fits the existing command traits.

Description

• Add terminal helper classes TerminalMode, TerminalInput, TerminalControl, and KeyPress to manage raw mode, read keys, and emit ANSI cursor/text sequences (e.g. stty handling, stream_select(), ESC sequences, ESC[H, ESC[2J, ?25l/?25h).
• Implement InteractiveMenu to render and drive single-select menus, checkbox multi-selects, and radio lists with highlighting and safe try/finally cleanup.
• Expose menu helpers via a new trait HasInteractiveMenus and wire it into both IGC\Tart\Laravel\StyledCommand and IGC\Tart\Symfony\StyledCommand.
• Update docs: add interactive menu examples to docs/guides/QUICK-REFERENCE.md, and mark completed items in docs/feature-todo.md related to menus and terminal helpers.

Testing

• Added unit tests tests/Unit/KeyPressTest.php for KeyPress::fromBytes() and tests/Unit/TerminalControlTest.php for TerminalControl sequences; the tests validate key parsing and ANSI sequence strings.
• No automated test run was executed in this environment, so test results are not available.
