feat(blueclaw): add Blue Claw provider

[eliteprox]

Adds BlueClaw, an OpenAI-compatible provider built on the Livepeer network (https://openai.blueclaw.network/v1) serving open Qwen models. Auth is a bearer token from BLUECLAW_API_KEY.

Two models, both verified live against the endpoint today:

• Qwen/Qwen3.6-35B-A3B-FP8 — context 131072 (read from the vLLM max_model_len error)
• Qwen3.6-27B — context 196608

For each I confirmed chat completions, streaming, and tool calls (finish_reason: tool_calls with a real function call). Reasoning comes back in a separate reasoning field; I left interleaved off since the field name is not one of the two the schema allows. No cost block — it is a free fair-use beta with no published pricing, so I would rather omit it than guess. release_date uses the underlying Qwen3.6 dates; limits/modalities reflect what the FP8 text endpoint actually serves (text only, narrower context than the native model).

AUTOMATED REVIEW: Blocking merge: add the provider logo; factor both Qwen models through their existing canonical base_model; add explicit provider-specific reasoning_options; and do not copy combined context length into limit.output without provider evidence.
