List the caller's model working set
Use when: caller wants the models the user actually works with — models any of their gates route to (in use) plus models they pinned from the catalog (added)
Returns one row per working-set model with membership flags: inUse (referenced by at least one of the caller’s gates — primary or fallback — computed live, never stored), added (manually pinned from the catalog), gateCount, and addedAt. Enrich against /v1/registry for pricing/display data.
Authorizations
