Classic298 7ef0530b24 fix: handle urllib3-future 4-element socket options in SSRF-safe web loader (#26796)
_ssrf_safe_new_conn unpacks each entry of self.socket_options straight into socket.setsockopt(), which accepts exactly 3 positional arguments. urllib3-future, a drop-in fork that shadows the urllib3 package whenever it is installed (for example as a dependency of niquests pulled in through a tool or function's requirements), declares its default socket options with a per-protocol 4th element: [(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1, "tcp")]. Its own _set_socket_options() strips that element before calling setsockopt(), but our override does not, so with urllib3-future present every synchronous web fetch (fetch_url, web search loading) fails on connect with "TypeError: setsockopt() takes exactly 3 arguments (4 given)" and returns empty content.

Mirror urllib3-future's handling in the override: for 4-element options whose last element is a protocol string, apply "tcp" options truncated to the first 3 elements and skip "udp" options (all sockets created here are SOCK_STREAM). Plain 3-element options, and any other shapes stock urllib3 would accept, are passed through unchanged, so behavior with stock urllib3 (which only ever uses 3-element tuples) is identical.

Verified locally: with urllib3-future installed the loader previously raised the TypeError on every URL and now fetches successfully; with stock urllib3 2.3.0 and 2.7.0 fetches behave the same before and after.

Note: #26015 reported this same crash but attributed it to stock urllib3 2.x, which only uses 3-element tuples; the 4-element form comes from urllib3-future shadowing urllib3.

Fixes #26791
