 Cache component lists in ProxyProvider (#3479) 
* fix: cache component lists in ProxyProvider to avoid redundant backend connections

Every call_tool through a proxy was triggering _list_tools() to resolve
the tool by name, opening a full MCP session just for the lookup, then
opening a second session for the actual execution. This caches component
lists on the ProxyProvider with a configurable TTL (default 300s),
cutting backend handshakes in half for repeated calls.

* docs: document component caching and session reuse for proxy providers

* fix: add sleep in cache TTL test for Windows clock resolution

* docs: clarify cache scope and dynamic backend guidance
