kevinveenbirkenbachandClaude Opus 5 3016388bd9 feat(wordpress): route server-side OIDC to an onion issuer through Tor
daggerhart-openid-connect-generic calls wp_remote_post() against
http://auth.<onion>/.../token, which bottoms out in libcurl -- and libcurl
refuses a .onion host at name resolution (RFC 7686) before /etc/hosts,
extra_hosts or DNS is consulted. The result is cURL error 6, which WordPress
turns into WP_Error('http_request_failed') and a bounce to
/wp-login.php?login-error=http_request_failed. Five specs of WordPress 0 in run
31340965955 failed on that single cause, 60 occurrences in the log.

Only a configured proxy makes curl skip the check, and socks5h:// hands the name
to Tor. The mu-plugin hooks http_api_curl because http_request_args cannot
express a proxy and WP core's WP_HTTP_Proxy hardcodes CURLPROXY_HTTP, so SOCKS5
is reachable only on the raw handle. env.j2 sets WORDPRESS_OIDC_SOCKS_PROXY only
when the issuer is an onion, so a clearnet deployment never routes through Tor.

Deliberately not adding the onion_oidc_socks include: 238b8b41f established it
is a no-op for this client, since libcurl never reads /etc/hosts here.

Depends on 1bb31fba4 -- without it swarm renders socks5h://host.docker.internal,
which is unreachable from inside the overlay.

The plugin's behaviour is unexercised: syntax checked, never run.
