LGTM. We should probably create a preview tag to test this before merging?

Description
Configures axios and undici proxy agents with connection pool limits and idle timeouts to prevent connection accumulation. The undici agents already had
keepAliveTimeout: 5000configured, but we're missing connection limits and axios was using Node's default agent with unlimited sockets and no idle timeout. This caused connections to accumulate over time.This PR adds
maxSocketsandmaxFreeSocketsto bound the connection pool, a matching 5 second idletimeout, and LIFO scheduling to naturally cycle out older connections.connectionslimit of 50 were also added to undici agents (defaultAgent and ProxyAgent). In addition, it also passes theforceIpv4Firstsetting to the proxy agent which previously overwrote that option, breaking the IPV4-first resolution when both proxy and `forceIpv4First were enabled.How Has This Been Tested?
(no need tbh).
