- Add reuse parameter to Display.init() for all backends - PygameDisplay: reuse existing SDL window via class-level flag - TerminalDisplay: skip re-init when reuse=True - WebSocketDisplay: skip server start when reuse=True - SixelDisplay, KittyDisplay, NullDisplay: ignore reuse (not applicable) - MultiDisplay: pass reuse to child displays - Update benchmark.py to reuse pygame display for effect benchmarks - Add test_websocket_e2e.py with e2e marker - Register e2e marker in pyproject.toml
