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).
