Triage channels now compute a 3-state delivery decision per recipient
(wake / observer / skip) instead of the binary wakeup flag, and route
according to:
1. author never gets back their own message → skip
2. wake_mapping member (on-duty) → wake
3. mention (NEW: was 'skip' for triage before) → wake
4. Center-scoped admin (at most 1) → observer
5. anyone else → skip
(was 'deliver wake=false')
Skipping means the websocket emit is omitted entirely — the recipient's
openclaw plugin never sees the message and the agent's session stays
free of background noise. Observer means delivered with wakeup=false
(silent UI / no model dispatch on the plugin side).
## What this PR ships
### realtime/realtime.gateway.ts
- new `computeDelivery()` returns DeliveryDecision = 'wake'|'observer'|'skip'
- old `computeWakeup()` kept as a deprecated wrapper for callers that
still want the boolean answer (treats observer + skip as false)
- `emitMessageCreated` accepts `adminUserId?: string|null` and now
short-circuits on 'skip' (no socket emit at all)
- general kept its current behavior; custom kept its current behavior
(members not in wake_mapping become observer instead of `wake=false`)
— the user-visible bit is just that the response field is the same
`wakeup: boolean`; the explicit 'skip' is new for triage
### common/center-auth.ts
- `fetchAdminEmail()` calls GET `${center}/auth/admin-email` with the
existing x-api-key (same auth as introspect/resolve-names). Returns
`{email, userId}` or `null` on either "no admin" or any error
### common/admin-cache.service.ts (NEW)
- `AdminCacheService` — in-memory cache, 1-day TTL, lazy refresh.
`get(force=true)` bypasses TTL for cli-triggered refresh
- exposed by MessagingModule
### messaging/messaging.controller.ts
- non-rotating branch threads `adminUserId` into emitMessageCreated
### cli/admin-refresh.ts (NEW)
- `node dist/cli/admin-refresh.js` — force-refresh cache and print
before/after JSON. Use after a Center `user set-admin` so triage
delivery picks up the new admin without waiting for 24h TTL
