Gun pool validation

The previous unique origin registry forced concurrent HTTP/1 requests onto one connection.
Pool identity omitted proxy routes and credentials, allowing incompatible routes to reuse a connection.
Gun 2.2 CONNECT requests require their tunnel stream reference on subsequent requests; Tesla's bundled Gun adapter does not preserve it.
CONNECT and SOCKS5 setup returned before the destination tunnel was ready and did not pass authentication credentials.
The existing global max_connections limit and idle reclaimer bound HTTP/1 sibling and many-host connection growth.
SOCKS4 is not supported by Gun 2.2 and is now rejected explicitly by the Gun adapter.
Gun reports a stale stream error to the process that calls cancel/2; pool workers must consume that reply so one HTTP/2 cancellation cannot terminate other multiplexed requests.
Streamed uploads must be registered before body enumeration and cancelled if enumeration exits, throws, or raises, otherwise a partial HTTP/1 request can remain reusable.
