fix(agents): finish sanitized config migration — GatewayClient also reads agents-sanitized.json

The previous commit f4bee44 updated AgentService.cs but missed
OpenClawGatewayClient.cs which also reads agent IDs and model config
from the raw openclaw.json. Both LoadAgentIdsFromConfig() and
GetAvailableModels() now default to /etc/nexus/agents-sanitized.json.

This completes the P4 migration: Nexus no longer needs read access to
openclaw.json for any code path.

-# CD v3 — 2026-06-13
-#
-# Triggers:
-#   1. AUTOMATIC after successful CI on main (workflow_run)
-#      → Uses safe defaults: patch bump, all services, main ref.
-#      → Commits marked with [skip ci] are filtered at job level
-#        (prevents version-bump loops).
-#   2. MANUAL via workflow_dispatch with full parameter control.
-#
-# Concurrency: one deploy at a time.
-#   Queued deploys wait — no race conditions with parallel builds.
-#
-# Version Management:
-#   The VERSION file in the repo root is the single source of truth.
-#   Version bumps happen in the Dev workflow BEFORE merge to main.
-#   The deploy workflow only reads, validates, and logs the version.
-#   The [skip ci] filter remains as a safety layer for auto-triggers.

 ## API endpoints
 
+### MCP Agent Data Plane
+
+Nexus exposes an MCP endpoint at `/mcp` for agent-facing board operations.
+It uses the official `ModelContextProtocol.AspNetCore` SDK with stateless
+streamable HTTP transport. Tools are a thin facade over `ITaskBridgeService`;
+they must not duplicate board business logic.
+
+Auth follows the bridge rules: requests provide `X-Agent-Id` and/or
+`X-Nexus-Api-Key`. Secrets stay in OpenClaw/Gateway config and are never
+embedded in frontend code.
+
+Registered tools:
+
+| Tool | Purpose |
+|---|---|
+| `nexus_get_board` | Full task board |
+| `nexus_agent_overview` | Waiting/stale workflow overview |
+| `nexus_get_task` | Single task |
+| `nexus_get_children` | Child tasks for a parent |
+| `nexus_get_activity` | Task activity history |
+| `nexus_create_task` | Create parent/standalone task |
+| `nexus_create_child_task` | Create visible delegation child task |
+| `nexus_update_status` | Update status using the canonical enum only |
+| `nexus_append_activity` | Append checkpoint/activity |
+| `nexus_handoff` | Handoff to a known agent |
+
+The compatible `/api/bridge` HTTP facade remains available for internal
+diagnostics and transition clients. New agent integrations should use MCP;
+`/api/dashboard` is UI/admin surface, not an agent contract.
+
+### Mission Control Gateway Plane
+
+Nexus keeps the Browser -> Nexus -> OpenClaw boundary: the frontend never talks
+to OpenClaw directly. Read-only Gateway status is exposed through
+`GET /api/dashboard/gateway`; it reports reachability, discovered Gateway
+version and the optional `Integrations:OpenClaw:RequiredVersion` pin. A set pin
+does not mutate production config, but makes protocol drift visible in the UI.
+
+Agent activity shown as "Thinking" is redacted before display. Lines containing
+token, password, bearer, authorization, API key or secret markers are replaced
+with a redaction marker. Persisted audit-worthy events should be written as
+short Activity entries, not raw session transcripts.
+
+Nexus activity updates stream live through the Dashboard SSE channel and are
+filtered by explicit `agentIds`. Gateway session history is read-only fallback
+data: it is fetched on demand, redacted before display and not persisted as a
+long-term raw transcript. Agent "Now" and "Today" summaries are deterministic
+derivations from redacted Nexus activity plus redacted Gateway history; Nexus
+does not call an LLM to summarize this feed.
+
+Config writes and approval actions are owner-only. Config saves validate before
+replacement, keep a `.bak` when an existing file is replaced, write audit events
+without file contents or secrets and return structured `validation`, `backup`
+and `reloadCheck` results. Workspace Markdown hot reload is currently reported
+truthfully as `not_supported`; JSON validation exists in the save path but JSON
+files are not exposed unless they are explicitly allowlisted for editing.

 Deployment can happen automatically or manually:
 
-#### Auto-Deploy (after successful CI on main)
+#### Auto-Deploy (after successful CI jobs on main)
 
-- Triggered by `workflow_run` after `CI - Build & Test` succeeds on `main`
+- Runs as the final `Deploy Nexus` job in `.gitea/workflows/ci.yaml`
-- Uses safe defaults: `patch` bump, all services, main ref
+- Starts only after backend, frontend, and security jobs succeed on `main`
-- Skips automatically if the triggering commit contains `[skip ci]` (version-bump commits)
+- Deploys the current `main` version after CI succeeds.
-- The version-bump commit itself uses `[skip ci]` → no infinite CI→Deploy→Bump→CI loops
+- This replaces `workflow_run`, which did not create deploy runs in this Gitea 1.26.3 installation.
+- The deploy script reads `VERSION`; it does not mutate Git, bump versions, or create tags
 
 #### Manual Deploy (`workflow_dispatch`)
 
-1. DevOps triggers `Deploy to Production` in Gitea Actions (or Iris auto-approves)
+1. DevOps triggers `Deploy Nexus Manual` in Gitea Actions
-2. Chooses version bump type: patch (default) / minor / major
+2. Workflow validates `VERSION`, builds and deploys `main`
-3. Optionally scopes to a single service or specific git ref
+3. Health check + smoke test verify the deployment
-4. Workflow bumps VERSION, creates git tag, builds and deploys
-5. Health check + smoke test verify the deployment

-### Known Issue: Gateway Bind = loopback
+### Resolved Routing Issue (2026-07-09)
 
-The Gateway binds to `127.0.0.1` (`gateway.bind: "loopback"`). This means it only listens inside the gateway container's loopback interface.
+The old `host.docker.internal:18789` route was unreachable because no usable host port was published. The Gateway is now reached directly by its container DNS name.
 
 | Scenario | Works? | Why |
 |----------|--------|-----|
-| Gateway with `--network host` | ✅ Yes | Process sees host's 127.0.0.1 directly |
+| `host.docker.internal:18789` | ❌ No | No reachable host listener on the VPS |
-| Gateway with `-p 18789:18789` + loopback bind | ❌ No | Port forward sends to container IP, not loopback |
+| `openclaw-gateway-bao:18789` in `openclaw_default` | ✅ Yes | Direct container-to-container routing via Docker DNS |
-| Gateway with `-p 18789:18789` + lan bind | ✅ Yes | Listens on all interfaces including container IP |
 
-**Fix**: Change `gateway.bind` from `"loopback"` to `"lan"` (binds `0.0.0.0`):
+The Gateway must listen on its container interface (`gateway.bind: "lan"`):
