feat(hook): expand IAT hook coverage with TLS bypass, connect/recv hooks, and logging

Adds connect_hook, connectex_hook, recv_hook, ssl_patch, tls_bypass, lsx, ea_stub,
and origin_spy modules to intercept EA's TLS and socket layers in addition to
getaddrinfo. Adds DLL-level logging to C:\openfut_hook.log for debugging. Also
patches windows-sys feature flags to include Cryptography and Threading APIs needed
by the new hooks.
