The web-wasm-freshness gate (#93) false-failed because the Bevy wasm build
baked in machine-specific absolute source paths — the cargo registry
(/home/<user>/.cargo/registry/...), the rustup std sources (~/.rustup/...),
and this checkout — so CI's rebuild (under /workspace, /root) never matched the
committed bytes even with identical pinned tool versions.
build_wasm.sh now exports CARGO_ENCODED_RUSTFLAGS with three --remap-path-prefix
rules (cargo home -> /cargo, rustup home -> /rustup, repo -> /build) so the
embedded paths are identical on any machine. It re-states the
getrandom_backend cfg because a *_RUSTFLAGS env var replaces (not merges with)
.cargo/config.toml's target rustflags.
Regenerated all four artifacts with the remap applied — verified zero
machine-specific paths remain (only canonical /cargo + /rustup prefixes), which
is the precondition for the gate's byte-for-byte rebuild-and-diff to match
across machines.
