// buildTrackerMappingConfig wires the tracker-mapping agent (catalog
// identification) and the third-party disambiguation agent that the
// tracker-mapping worker uses to promote patterns to org ThirdParties.
// Both are opt-in: deployments that do not set
// `llm.tracker-mapping.provider` get zero configs (nil LLM client) so
// the worker runs without agent fallback.
//
// Both agents are sourced from the same `tracker-mapping` config slot
// because they share the LLM client, model, and lifecycle. The
// disambiguation agent has no Firecrawl/DB tools, so its config
// surface is narrower and it lives in the cross-domain pkg/thirdparty
// package.
