Speech-to-Speech: Hydra V1.1 released, ?model=hydra deprecated

Hydra V1.1 is the current release of the realtime speech-to-speech model. New integrations should connect with ?model=hydra-v1.1:

wss://api.smallest.ai/waves/v1/s2s?model=hydra-v1.1&api_key=<SMALLEST_API_KEY>

The session protocol (event catalog, session.configure shape, tool calling, interruption handling) is identical to the original hydra, so switching is a one-parameter change on the query string.

Read from the provider's text and verified a second time against the quoted lines.
