NewProxyBlobStore built a fresh http.Client and http.Transport on every
call, and it is called once per registry request because the routing
repository is created per request. So no connection to the hold or to a
presigned S3 URL was ever reused: every XRPC call and every part upload
paid a TCP and TLS handshake, HTTP/2 was never negotiated, the idle pool
settings were dead config, and each discarded transport kept its idle
sockets open for the full 90s timeout.
One package-level transport and client now back every store. Settings
are unchanged; ForceAttemptHTTP2 is explicit to document intent. The
load balancer negotiates h2 on the frontend (416ba4a) but reaches the
hold over HTTP/1.1, so multiplexing stops at the LB. The win is the
handshake and socket churn, not multiplexing.
The struct field stays per-instance so tests can substitute a client.
