## Installation

```bash
npm install @ruvector/wasm-unified
# or
pnpm add @ruvector/wasm-unified
# or
yarn add @ruvector/wasm-unified
```

## Quick Start

```typescript
import { createUnifiedEngine } from '@ruvector/wasm-unified';

// Create and initialize the unified engine
const engine = await createUnifiedEngine();
await engine.init();

// Use attention mechanisms
const Q = new Float32Array([1, 2, 3, 4]);
const K = new Float32Array([1, 2, 3, 4]);
const V = new Float32Array([1, 2, 3, 4]);
const output = engine.attention.scaledDot(Q, K, V);

// Use learning capabilities
engine.learning.btspOneShotLearn(pattern, 1.0);

// Simulate nervous system
const neuronId = engine.nervous.createNeuron({ neuronType: 'excitatory' });
engine.nervous.step();

// Manage economy
const balance = engine.economy.creditBalance();
engine.economy.stakeDeposit(100);

// Exotic computations
const qstate = engine.exotic.quantumInit(4);
const measured = engine.exotic.quantumMeasure(qstate);

// Cleanup when done
engine.dispose();
```

## Type Safety

All APIs are fully typed with TypeScript:

## Benchmarking

```typescript

// Benchmark specific mechanism
const results = await benchmarkAttention('flash', 1024, 100);
console.log(`Flash attention: ${results.avgTimeMs}ms avg, ${results.throughputOpsPerSec} ops/sec`);

// Benchmark all mechanisms
for (const mechanism of listAttentionMechanisms()) {
  const result = await benchmarkAttention(mechanism, 512, 50);
  console.log(`${mechanism}: ${result.avgTimeMs.toFixed(3)}ms`);
}
```

## Configuration

```typescript
