channel enum + X_TYPES + realtime XType gain 'dm'. dm channels are
forced private (never public) and non-unique (no dedup; create()
always makes a fresh one). computeWakeup: dm wakes every non-author
participant unconditionally (no rotation / no wake_mapping). The
message.created realtime payload now carries xType so the plugin can
treat dm specially.

Channel.closed; POST /channels/:id/close (member-only); message/command
posts on closed channel -> 409 {error:channel_closed}; GET history still
allowed; listForUser carries closed.

Channel.x_type enum(general|work|report|discuss|triage|custom); required
and validated on channel creation (400 if missing/invalid).

- Channel.isPublic (default false): public channels visible to all guild
members; non-public only to explicit members
- GET /channels filters to channels visible to the requesting user
