Real-time queries can now be registered, listed, and deleted from the SDK instead of only consumed, and the two streaming consumers collapse into one class. - NewsDataApiWebSocket takes a NewsDataApiClient and adds websocket_register(), websocket_fetch(), and websocket_delete(). They go through the client's _request(), which gains a `method` argument for POST/DELETE, so they inherit its session reuse, retry/backoff, and exception mapping. Registration always targets the latest feed. - registration_id moves from the constructor to stream()/stream_async(), so a single instance can register a query and then stream it. - NewsDataApiWebSocketAsync merges into NewsDataApiWebSocket as stream_async(), and the _BaseNewsDataApiWebSocket base class is gone. Sync and async connections are tracked separately so `with` and `async with` only ever close their own socket. - Fix the stream payload field: frames carry articles under `results`, not `items`, so the consumer would have yielded nothing against the live server. Each frame is now yielded whole; malformed frames are skipped instead of ending the stream. - websockets becomes a required dependency rather than the optional `websocket` extra. It needs Python 3.10, which becomes the floor (3.8 and 3.9 are both past end of life); classifiers, the CI matrix, ruff's target-version and mypy's python_version follow. - Version 0.3.0: 0.2.3 is already published on PyPI, and the raised Python floor plus the new required dependency call for a minor bump.
