Runtime/E2E testing of the ralph-tui TUI

Use this when a change must be proven in the real TUI (watch mode, engine status labels, pause/resume, shutdown/quit paths) rather than with unit tests.

Build & run

cd /path/to/ralph-tui && bun run build      # produces dist/cli.js

Run the built CLI (not bun run dev) so behaviour matches shipped code:

bun /path/to/ralph-tui/dist/cli.js run [flags]
