## Summary
Adds a `subscriptions` getter to `ServerWebSocket` that returns an array
of all topics the WebSocket is currently subscribed to.
## Implementation
- Added `getTopicsCount()` and `iterateTopics()` helpers to uWS
WebSocket
- Implemented C++ function `uws_ws_get_topics_as_js_array` that:
- Uses `JSC::MarkedArgumentBuffer` to protect values from GC
- Constructs JSArray directly in C++ for efficiency
- Uses template pattern for SSL/TCP variants
- Properly handles iterator locks with explicit scopes
- Exposed as `subscriptions` getter property on ServerWebSocket
- Returns empty array when WebSocket is closed (not null)
## API
```typescript
const server = Bun.serve({
websocket: {
open(ws) {
ws.subscribe("chat");
ws.subscribe("notifications");
console.log(ws.subscriptions); // ["chat", "notifications"]
ws.unsubscribe("chat");
console.log(ws.subscriptions); // ["notifications"]
}
}
});
```
## Test Coverage
Added 5 comprehensive test cases covering:
- Basic subscription/unsubscription flow
- All subscriptions removed
- Behavior after WebSocket close
- Duplicate subscriptions (should only appear once)
- Multiple subscribe/unsubscribe cycles
All tests pass with 24 assertions.

This changes `publishToSelf` to be `false` by default instead of `true`.
This is a breaking change because it means that `ws.publish("foo", "bar")` will exclude `ws` from the list of websockets to broadcast.
We are making this change because many people asked for this and were confused by the status quo - that `w.publish` publishes to self.
Previously, this defaulted to "uint8array", so this shouldn't be a breaking change unless you make use of `.slice()` in which case it will now be a reference to the same ArrayBuffer rather than a clone.
The rationale for this change is most usages of Uint8Array on the server need a little more than just the bytes. Many npm packages expect Buffer rather than Uint8Array. Directly returning it for binary websocket messages is faster than creating another one.
