autoop: +w <prefix>:<mask> channel list mode grants status on join

+//! autoop — the channel list mode `+w <prefix>:<hostmask>` grants a status prefix
+//! to matching users the moment they join, e.g. `+w o:*!*@trusted.host` auto-ops
+//! them, `+w v:*!*@*.friend` auto-voices. The list lives on the channel (like +b,
+//! stored verbatim); this module applies it on join via the server-authority mode
+//! path. Reference: InspIRCd's `m_autoop`. Original native Rust.
