WebAssembly bindings for [ruvector-verified](https://crates.io/crates/ruvector-verified) — proof-carrying vector operations in the browser. Verify vector dimensions, build typed HNSW indices, and create 82-byte proof attestations entirely client-side with sub-microsecond overhead.

## Quick Start

```js
import init, { JsProofEnv } from "ruvector-verified-wasm";

await init();
const env = new JsProofEnv();

// Prove dimension equality (~500ns)
const proofId = env.prove_dim_eq(384, 384);

// Verify a batch of vectors (flat f32 array)
const flat = new Float32Array(384 * 100); // 100 vectors
const count = env.verify_batch_flat(384, flat);
console.log(`Verified ${count} vectors`);

// Create 82-byte proof attestation
const att = env.create_attestation(proofId);
console.log(att.bytes.length); // 82

// Route proof to cheapest tier
const routing = env.route_proof("dimension");
console.log(routing); // { tier: "reflex", reason: "...", estimated_steps: 1 }

// Get statistics
console.log(env.stats());
```
