Type-safe WebSocket Abstraction

Reusable WebSocket wrapper with builder pattern, exponential/linear/constant backoff strategies, JSON/Bebop serialization, SolidJS reactive effects, heartbeat, and auto-reconnection. Works standalone in any TypeScript project.

# WebSocket

Shared, type-safe WebSocket abstraction with reconnect, buffering, heartbeat,
serialization, and Solid lifecycle helpers. Import its public API through the
`@macro-inc/collaboration/websocket` export.

## Basic Usage

```typescript
import { JsonSerializer, WebsocketBuilder, WebsocketEvent } from '@macro-inc/collaboration/websocket';

const ws = new WebsocketBuilder('ws://localhost:5000')
  .withSerializer(new JsonSerializer<SendType, ReceiveType>())
  .build();

ws.addEventListener(WebsocketEvent.Message, (_socket, event) => {
  console.log('Received:', event.data);
});

ws.send({ type: 'hello' });
```

## Builder Pattern

```typescript
import { ExponentialBackoff, WebsocketBuilder } from '@macro-inc/collaboration/websocket';

const ws = new WebsocketBuilder('ws://localhost:50
