switch to Pyodide — run byte_emergence_demo.py 100% verbatim in browser

User asked: 'can we use the Python code 100% identical, even if not 60fps?'
Yes — Pyodide loads numpy in WebAssembly and runs the original engine_step,
H, H_joint, emergence functions byte-for-byte. ~20-30 fps tick rate, no
JS porting, no server.

The previous JS port had divergence risk (XOR semantics, integer truncation,
RNG implementation). With Pyodide the result is provably identical to the
terminal demo — same numbers, same scatter pattern (zigzag from
'w ^ (L >> 1)' XOR coupling is the actual behavior).

First paint trade-off: ~5 s Pyodide+numpy download (cached after first
visit). UI shows progress bar during init, slider/reset disabled until
ready.

 ## Tech
+- Static HF Space (`sdk: static`) — no cold start.
+- **Pyodide** — runs `byte_emergence_demo.py` 100% verbatim in the browser via WebAssembly. numpy included.
+- First paint after Pyodide load (~5 s download, then cached): metrics tick at ~20-30 fps.
+- 16-bin histogram entropy, 256-sample window per tick.
+- Reproducible noise: `np.random.default_rng(t)` seeded by frame index — same as the Python original.
