fix(agent-team): repair Slack listener block_actions matcher; add dedicated Slack app

The Socket Mode inbound listener crashed at registration time on first live
run: `@app.action({})` raised `BoltError: action ({}) must be any of str,
Pattern, and dict` under slack_bolt 1.28.0, killing the listener thread (the
whole inbound answer path — message/app_mention/block_actions — went down,
caught only by the coordinator's respawn watchdog). serve() is marked
`# pragma: no cover - live socket`, so this was never exercised until the R720
bring-up. Replace the unsupported empty-dict matcher with a catch-all
`re.compile(r".*")` action_id regex; handle_event still does the real filtering
+ AUTHZ-01 owner-allowlist gate, so over-matching is safe.

Verified on sh-secrev: listener connects (live Socket Mode WebSocket), outbound
chat.postMessage works, 0 errors. /sh-security-review PASS (no confirmed
critical/high; matcher change introduces no new findings).

Also adds the dedicated Slack app (manifest + README) backing the clarifier
gate — "Sea Haven agent-team" (A0BC7AT8NUD), workspace-scoped install to avoid
the Enterprise-Grid `scope_not_allowed_on_enterprise` org-install trap — and
patches the provisioning runbook's stale langgraph pin (1.1.10 -> 1.2.5).

+# agent-team Slack app
+
+Dedicated Slack app backing the Plane-2 clarifier human-gate (Socket Mode).
+Kept separate from the webhook-only **Tech Notifications** app (`A0ARYQZU3KJ`)
+that the nightly secrev sweep uses, to isolate the two-way bot's trust surface.
+
+| Field | Value |
+|---|---|
+| App name | Sea Haven agent-team |
+| App ID | `A0BC7AT8NUD` |
+| Org / team | seahaven (`E0A524V806L`) |
+| Manifest | [`agent-team-manifest.json`](./agent-team-manifest.json) (source of truth) |
+| Settings | https://api.slack.com/apps/A0BC7AT8NUD |
+
+## Why these scopes (verified against the code)
+
+`agent_team/transport/slack_listener.py` subscribes over Socket Mode to
+`message`, `app_mention`, and Block Kit `block_actions`; `slack_live.py` posts
+questions via `chat.postMessage`.
+
+| Capability | Scope / setting | Why |
+|---|---|---|
+| Post clarifier questions | `chat:write` | `slack_live.py` `chat.postMessage` |
+| Hear thread replies in the channel | `channels:history` / `groups:history` + `message.channels`/`message.groups` events | `@app.event("message")` |
+| Hear DM replies | `im:history` + `message.im` event | DM answer path |
+| Hear @mentions | `app_mentions:read` + `app_mention` event | `@app.event("app_mention")` |
+| Block Kit button/select answers | `interactivity.is_enabled` | `@app.action({})` |
+| Inbound WebSocket | `socket_mode_enabled` + an app-level token w/ `connections:write` | VPN-only box, no public HTTPS endpoint |
+
+Inbound auth is NOT scope-based: AUTHZ-01 (`AGENT_TEAM_SLACK_OWNER_IDS`) gates
+the *sender* and fails closed. Socket membership alone is never authorization.
+
+## Remaining manual token mints (operator, in browser)
+
+Both produce secrets — paste them straight into `~/secrev.env` on the box
+(mode 600), never into shell history.
+
+1. **Bot token (`xoxb-`)** — https://api.slack.com/apps/A0BC7AT8NUD/oauth →
+   *Install to Workspace* → approve → copy the **Bot User OAuth Token** →
+   `SLACK_BOT_TOKEN`.
+2. **App-level token (`xapp-`)** — https://api.slack.com/apps/A0BC7AT8NUD/general
+   → *App-Level Tokens* → *Generate Token and Scopes* → add scope
+   `connections:write` → copy → `SLACK_APP_TOKEN`.
+3. **Channel** — create/choose the clarifier channel, `/invite @agent-team`,
+   copy its `C0...` id → `SLACK_CHANNEL_ID`.
+4. **Owner allowlist** — `AGENT_TEAM_SLACK_OWNER_IDS` = Adam's Slack user id
+   (`U0A3SC48T47`), comma-separated if more than one. Gate fails closed if empty.
+
+## Reproduce / update the app from the manifest
+
+```bash
+TOKEN=$(python3 -c "import json;print(json.load(open(os.path.expanduser('~/.slack/credentials.json')))['E0A524V806L']['token'])")
+# validate
+curl -s -X POST https://slack.com/api/apps.manifest.validate \
+  -H "Authorization: Bearer $TOKEN" --data-urlencode "manifest=$(cat agent-team-manifest.json)"
+# update existing app
+curl -s -X POST https://slack.com/api/apps.manifest.update \
+  -H "Authorization: Bearer $TOKEN" \
+  --data-urlencode "app_id=A0BC7AT8NUD" \
+  --data-urlencode "manifest=$(cat agent-team-manifest.json)"
