 * List the workspace inference profiles a plugin can route to, in the order the
 * `/model` picker presents them (`llm.profileOrder` first, then the rest
 * alphabetically). Metadata-only entries without a provider, model, or mix are
 * not routing targets, so plugins never see them. Disabled profiles are
 * included and flagged via
 * {@link ModelProfileInfo.isDisabled}; weighted "mix" profiles are included and
 * flagged via {@link ModelProfileInfo.isMix}, since a mix is itself a valid
 * routing target (it resolves to one constituent per conversation).
 *
 * Reads the live in-memory config, so the result reflects the current profile
 * set each time it is called.
