Add common catalog query layer and enricher service

Introduce an API-style data layer for the global common tracker pattern
and common third party catalogs: typed filters, order fields, CursorKey,
cursor-paginated Load and CountAll, plus by-id enrichment re-queue and a
scoped reset/remap helper for a banner's tracker patterns. These reuse
the same page.Cursor/filter/order types the GraphQL API consumes, so a
future proboctl API can back them unchanged.

Extract the common-pattern enrichment logic out of the worker into a
CommonPatternEnricher service so it can run either from the background
queue or synchronously over a known set of ids; the worker becomes a
thin poller that delegates to it.

Extract the LLM client and tracker-agents config wiring into
pkg/agentsbuild so probod and other binaries build agents identically;
probod now delegates to it.

-// buildTrackerAgentsConfig wires the tracker agents that share one LLM
-// client and model: the tracker-mapping agent (catalog identification),
-// the common-pattern enrichment agent (description research), and the
-// third-party disambiguation agent that the tracker-mapping worker uses
-// to promote patterns to org ThirdParties. All are opt-in: deployments
-// that do not set `llm.tracker-mapping.provider` get zero configs (nil

-// The agents are sourced from the same `tracker-mapping` config slot
