Per-instance timeout parameter actually mutates global state

High Severity

The timeout parameter on ClobClient.__init__ suggests per-instance configuration, but set_http_timeout replaces a module-level global _http_client shared by all instances. Creating a second ClobClient with a different (or no) timeout silently overrides the first client's timeout. Ironically, this can reintroduce the exact duplicate-order problem the PR aims to fix — a user sets timeout=30 on one client, then another component instantiates a default client, resetting the timeout to httpx's default.

Old HTTP client not closed, leaking connections

Medium Severity

set_http_timeout replaces the module-level _http_client with a new httpx.Client without calling .close() on the old one. Since the client is created with http2=True, the old instance holds open HTTP/2 connections and associated resources (sockets, TLS state) that are never properly released, causing a resource leak.
