 * Agent engine API-key helpers (browser).

 * Named client helper for storing a bring-your-own provider key (Anthropic,
 * OpenAI, etc.) so the agent chat can run without a Builder connection or an
 * account. The key is persisted by the framework under the matching provider
 * key (e.g. ANTHROPIC_API_KEY) for the current user or org, exactly like the
 * LLM settings panel does — UI code should call this instead of hand-writing
 * a fetch to framework routes.
