The CLI now covers the whole Redmine 507 surface: `search TERM [-page N]` (operators pass through quoted), `messages send -title -to user1,user2 [-group/-email] [-file|-raw]`, plus the two secret helpers `webhook verify SIG` (delivery body on stdin, exit 0 only on a valid HMAC) and `sso verify SSO SIG` (prints the decoded Discourse Connect payload as JSON). The helpers run before client construction so they work with only their secret env set, no instance credentials needed. Usage text lists the new env vars. Part of Redmine 507 (Discourse Go client).
