"""Plugin LLM facade — host-owned LLM access for trusted plugins (``ctx.llm``).
``complete`` / ``complete_structured`` (text + image inputs, JSON schema validation)
and their async siblings. Provider/model/agent_id/profile are explicit keyword
arguments mirroring the host config shape; the host owns routing, auth, timeouts
and fallback, so the plugin never sees raw tokens or keys. Every override knob is
gated by the per-plugin ``plugins.entries.<id>.llm.allow_*_override`` trust flags
(fail-closed: a missing block means "no overrides"). Backed by
:func:`agent.auxiliary_client.call_llm`.
