(Migrated from gitlab.com)

/cg/tickers, /cmc/summary, /cmc/ticker loop all pairs with a per-pair stats + extensions fanout (N–2N round trips), uncached, on the 10-connection API pool → a burst pins the pool. Adds a shared 60s TTL cache (per-endpoint serialized response), modeled on the route_solver/orderbook caches, so the fanout runs at most once/minute.

Pagination (the other triage half) is deferred + flagged on the issue: these are aggregator complete-snapshot endpoints (CG/CMC expect every pair), so naive page-by-page would hide pairs — that's a format decision. The cache already removes the pool-exhaustion vector.

cargo check clean.
