multipleof4andClaude Opus 5.5 fd5694669a Fix: Dedupe concurrent searches for the same query with a SurrealDB lock ...

Two misses for the same query at once each ran their own search (ntfy
showed Search #24 and #25 for one image). An in-memory fix wouldn't
hold: a test of concurrent same-query requests on this project found
they share an isolate only ~25% of the time.

The rate-limit query is now one transaction that also claims a
per-query lock, so it's still a single SurrealDB round trip. Requests
that find the lock held write nothing (so aren't counted), poll until
it's released, then serve the image from R2. Write conflicts roll the
whole transaction back and are retried.
