What's changed

• Everything from Centrifugo OSS v6.9.4
• Fix panic when cache empty proxy is used in several namespaces.
• The change in Centrifugo OSS to no longer copy channel config structs on each call is a positive speedup for Centrifugo PRO as its struct is larger in size, eliminating possible regression of moving to Centrifugo PRO from the OSS version.
• Faster capability checks with regex rules — a capability rule with match: "regex" recompiled its pattern on every subscribe, publish, presence and history request. Compiled patterns are now cached.
• Channel inspector shows the server's own verdict on a channel name — the admin UI decided by itself whether a channel name passes channel_regex, and it could not do this correctly (a pattern channel is matched as a whole, the private prefix is trimmed first, and without a regex the server applies its own rules). The channel_options admin endpoint now returns name_valid and pattern, and the UI shows what the server says. The channel length limit is included in the verdict too.
• Updated dependencies.
