Gateway can forward user identity headers, plus a new ccr-gateway host mode

Gateway upstreams can pass your sanitised identity headers along, and a new ccr-gateway host mode takes its origin from --sdk-url.

What

An upstream configured with forwardUserIdentity now has sanitised identity headers, including x-claude-gateway-user-email, added to its outbound requests. A new ccr-gateway host kind takes its origin from --sdk-url.

Details
  • Config validation warns when forward_user_identity is set on a deployment where no session principal can exist, since the headers would then never be sent.
  • ccr-gateway reports the same missing-URL and rejected-URL errors as the existing ccr-session host kind.
  • Upstream 400 and 413 responses now get their own error-message mapping instead of a generic one.
