M2: admin console over ssh admin@ (users, sessions, moderation, plugins) (#3)

A privileged operator console reached as `ssh admin@host`, gated by route plus the $AGENTBBS_ADMINS allowlist (admin status is operator-granted only, never self-assigned in-band). It is a self-contained Bubble Tea model, not a hub plugin, so it never appears in the public menu. Sections (PRD §6): - Users & members: list accounts; b = suspend/ban (operators protected). Banned accounts are blocked at the hub and pod@ routes. - Sessions & pods: live in-memory session registry; k = disconnect. - Moderation & audit: admin action log + agent@ transcripts (tab to switch). - Config & plugins: runtime snapshot; space = enable/disable a plugin (persisted; filtered from the hub on next sign-in). Every privileged action is written to a new admin_actions audit table. store: + banned column, admin_actions and plugin_state tables, and the backing methods (ListUsers/SetBanned/RecentSessions/LogAdminAction/ RecentAdminActions/RecentChatsAll/DisabledPlugins/SetPluginDisabled), with unit tests. auth: admin allowlist helpers + tests. Docs in docs/admin.md; README M2 flipped to done. Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>

+# Admin console (M2)
+
+The admin console is a privileged operator surface reached over SSH:
+
+```
+ssh admin@bbs.profullstack.com
+```
+
+It is **not** a hub plugin — it never appears in the public menu. Access is
+gated by the route plus an operator allowlist, so a curious member who guesses
+the route still gets nothing.
+
+## Who is an admin
+
+Admin status is granted **only by the operator**, out of band, via an
+environment variable — it can never be self-assigned in-session:
+
+```
+AGENTBBS_ADMINS="anthony,ops"   # comma/space-separated account names
+```
+
+To open the console you must:
+
+1. connect as `admin@` (or `sysop@`), **and**
+2. present the SSH key of an account whose name is in `$AGENTBBS_ADMINS`.
+
+Anyone else gets `admin@ is restricted to operators.` and is disconnected.
+
+## Sections
+
+The console is a Bubble Tea TUI. Arrow keys (or `j`/`k`) move, `enter` opens a
+section, `esc` goes back, `q` quits, `r` refreshes the current list.
+
+### Users & members
+Lists accounts (newest first) with kind / premium / verified flags.
+
+- `b` — ban/unban the selected account. Banned accounts are blocked at login
+  on the hub and `pod@` routes. Operators cannot be banned.
+
+### Sessions & pods
+The **live** view of currently-connected SSH sessions (the in-memory registry,
+distinct from the historical audit trail in the DB).
+
+- `k` — disconnect the selected session (PRD §6 "terminate live sessions").
+  Your own session is marked `(you)` and is protected.
+
+### Moderation & audit
+- `tab` switches between the **admin action log** (every ban, kill, and plugin
+  toggle, with who/when) and recent **`agent@` transcripts** for review.
+- Bans are taken from the Users section.
+
+### Config & plugins
+- Read-only runtime snapshot: host, sandbox mode, pods engine, mail status,
+  admin allowlist.
+- `space` toggles a hub plugin on/off. The change is persisted (`plugin_state`
+  table) and takes effect on each member's next sign-in — disabled plugins are
+  filtered out of the hub menu.
+
+## Audit trail
+
+Every privileged action is written to the `admin_actions` table
+(`admin, action, target, detail, created_at`) and is visible in the
+Moderation & audit section. Connection metadata continues to land in the
+`sessions` table as before.
+
+## Persistence
+
+| Concern            | Where                                  |
+|--------------------|----------------------------------------|
+| Suspensions        | `users.banned`                         |
+| Plugin enable/disable | `plugin_state(id, disabled)`        |
+| Admin action log   | `admin_actions`                        |
+| Session audit trail| `sessions` (historical)                |
+| Live sessions      | in-memory registry (killable)          |
+
+## Not yet (future milestones)
+
+- AgentAd ops (creative approval, ledgers) — lands with M5.
+- Live operator takeover of an `agent@` chat — the transcripts are reviewable
+  here today; interactive takeover is future work.
+- Per-plugin config editing beyond enable/disable.
