List Agent Models Live

Request body for POST /agents/models/live.

Same two shapes as ValidateLlmRequest minus model - this endpoint lists every model the caller's credentials can see, it doesn't check a specific one. savedConnectionId bypasses the inline-apiKey requirement identically.

capability scopes which models the response should include:

• chat — runs the chat-capable + tool-capable filters; returns each model with its per-(provider, model) tuning matrix attached, since the FE renders temperature / reasoning controls off that blob.
• embedding — runs the embedding-capable filter; returns each model as {value, label} (no tuning matrix — embedding endpoints accept no temperature / reasoning controls).

A second validator rejects (provider, capability) pairs that contradict :data:PROVIDER_CAPABILITIES (e.g. provider=anthropic + capability=embedding) before the BE wastes a round-trip on a request the matrix already pinned as impossible.
