test(FN-7690): reconcile anthropic-compatible apiType assertions + de-slow retry test

Browse Source 
FN-7690 changed resolveApiType() to return the registered pi-ai key
"anthropic-messages" for anthropic-compatible providers (the bare
"anthropic" key is never registered and throws at stream time), but left
behind a stale JSDoc and a stale test expectation:

- custom-provider-registry.ts: update the FN-7689 buildCustomProviderModels
  comment that still described the anthropic/anthropic-messages drift as
  unresolved.
- provider-registration.test.ts: assert config.api === "anthropic-messages"
  (was still asserting the pre-fix "anthropic").

Also de-slow a retry-exhaustion test: the describe uses fake timers with
shouldAdvanceTime, so awaiting a 3-retry backoff (1s+5s+15s) burned ~21s of
real wall time. Drive the backoff with advanceTimersByTimeAsync instead
(Standing Rule: prefer fake timers over real time waits).
