Subject: pardes v2: the rewrite, complete and organized. src/ (core + three
 shells), test/ (snapshot parity harness + 18 frozen goldens). One sans-IO
 core, vaxis tty + SDL3 GPU native + wasm web shells, 18/18 parity with the
 purged prototype, 7.6k lines vs 12.1k. Fix: gui shell pre-sized the core at
 init so the greet-releasing resize never fired (blank panes until first
 interaction); live sessions now init at defaults and get the real grid as a
 resize event (the shell contract, documented on Options).
