sdivi-rust v0.2.51 — Binaryen-free WASM builds

A small maintenance release (M50) that lets bindings/sdivi-wasm build with
wasm-pack in network-restricted / corporate environments that lack the
binaryen toolchain (wasm-opt). No source or behaviour change; snapshot_version
stays "1.0".

Highlights

• Disabled wasm-opt post-processing in the wasm-pack release profile. By
  default wasm-pack build runs wasm-opt and, when binaryen isn't on PATH,
  tries to download it — which fails behind a corporate proxy/airgap and breaks
  the build. The size-optimised [profile.release-wasm] Cargo profile
  (opt-level = "z", fat LTO, codegen-units = 1) already provides the primary
  size reduction, so wasm-opt is now disabled via
  [package.metadata.wasm-pack.profile.release] wasm-opt = false. Source builders
  no longer need binaryen.

Size impact

Dropping the wasm-opt pass grows the bundler/node .wasm by ~10%
(≈1,531,484 → ≈1,679,707 bytes) but stays comfortably within the existing
1.75 MB (1,835,008-byte) per-target budget, with ~155 KB of headroom. The trade —
a fragile toolchain dependency for ~10% size — favours the project's primary
audience (corporate / network-restricted builders).

What did not change

• snapshot_version is still "1.0". Snapshot JSON, the 19-category contract,
  pattern_metrics, and DivergenceSummary are unchanged from v0.2.50.
• No public-API change, no new .sdivi/config.toml keys, no analysis behaviour change.
• The published @geoffgodwin/sdivi-wasm exposes the identical wasm-bindgen surface;
  only the codegen post-processing differs.
• The WASM dependency invariant (Rule 21) holds.
