fix(cloud-router): prevent local HF org models from being misrouted to OpenRouter (#213)

get_provider() previously routed any "/" model to OpenRouter, which caused
locally-served models (e.g. mlx-community/Qwen3.5-27B-4bit-DWQ) to be sent
to the cloud instead of localhost:8080.

Adds _LOCAL_HF_ORGS module-level allowlist covering mlx-community/,
bartowski/, unsloth/, and lmstudio-community/. Returns None early for
these before the openrouter "/" check.
