m3ultra 6ea7aa6dd4 core: build rhai without ahash/runtime-rng
rhai's default feature set is ["std", "ahash/runtime-rng"]. The second half
seeds hash maps from OS entropy, which is a run-to-run variation source
living under a crate whose whole promise is byte-identical replays — and it
pulls getrandom, which has no backend on wasm32-unknown-unknown, so the
browser build could not compile at all.

Dropping it leaves ahash on its compile-time seed. The canonical Neon
Precinct playthrough produces byte-identical events before and after, and
the suite is green.

# pulls getrandom, which has no default backend there). "std" is the rest of
