The PartsCatalogs ProxyAgent had no connect timeout, so a dead DataImpulse proxy
port stalled for undici's 10s default before the retry rotated to a fresh port
(prod: "ConnectTimeoutError ... 74.81.81.81:10628, timeout: 10000ms"). Three such
stalls exceed the caller's 25s decode budget, turning a transient bad port into a
hard decode failure.
Set an explicit 6s proxy connect timeout so retries rotate to a live port within
budget, and make the request timeout / retry count / connect timeout env-tunable
(PCAT_REQUEST_TIMEOUT_MS, PCAT_MAX_RETRIES, PCAT_PROXY_CONNECT_TIMEOUT_MS) with the
current values as defaults. Phase 2 of 4 on decode reliability.
