v0.3.9

Fixed openfang stop returning 401 when api_key is configured. Shutdown endpoint now allows loopback connections without authentication so the CLI can always stop the daemon it started.

Enriched GET /api/agents with model_tier, auth_status, ready, and last_active fields. Agents that use the kernel default model now show the actual resolved provider and model instead of "default".

Channel bridge now auto-routes messages to the "assistant" agent (or first available) when no default_agent is configured. Previously messages were silently dropped with a confusing error on fresh installs.

Added Gemini, xAI, Qwen, Perplexity, Cohere, Cerebras, and SambaNova to the CLI setup wizard. Previously only 11 of 29 supported providers were selectable during openfang init.
