d9a1640b10 CUB-200: sync CI workflows with dev branch
Some checks failed
Dev Build & Deploy / docker-build-push (pull_request) Has been skipped
Dev Build & Deploy / test-and-build (pull_request) Failing after 0s
- Overwrite dev.yml with dev's consolidated version (parameterized Go/Node versions, cleaner install steps)
- Add deploy-dev.yaml from dev (was missing on this branch)
- build-dev.yaml confirmed absent (was deleted on dev in PR #45)

6fd2d9bec4 Merge branch 'dev' into agent/dex/CUB-200-ws-gateway-client

d28d6e8dac CUB-200: implement WebSocket gateway client with v3 protocol
Some checks are pending
Dev Build / build-test (pull_request) Waiting to run
Dev Build / deploy-dev (pull_request) Blocked by required conditions
Replace REST poller with WebSocket client as primary gateway connection:

- wsclient.go: WebSocket client with v3 handshake (connect.challenge →
  connect → hello-ok), frame routing (req/res/event), JSON-RPC Send(),
  auto-reconnect with exponential backoff (1s → 30s max)
- sync.go: Initial sync via agents.list + sessions.list RPCs, merge
  session runtime state into AgentCardData, broadcast fleet.update
- events.go: Real-time event handlers for sessions.changed, presence,
  and agent.config — DB update first, then SSE broadcast
- client.go: REST poller retained as fallback (WS is primary)
- config.go: Add GATEWAY_WS_URL and OPENCLAW_GATEWAY_TOKEN env vars
- main.go: Wire WS client as primary, REST as fallback
- .env.example: Document new WS config vars

Fallback: If WS connection fails, seeded demo data + REST polling
remain available.

# Control Center — Architecture Context
## Current State
The Control Center backend uses a **dual-path gateway client** architecture:
- **Primary path**: WebSocket client (`gateway.WSClient`) connects to the OpenClaw gateway using WS protocol v3. It handles handshake, initial sync (agents.list + sessions.list RPCs), live event routing (sessions.changed, presence, agent.config), and automatic reconnection with exponential backoff.
- **Fallback path**: REST poller (`gateway.Client`) polls the gateway `/api/agents` endpoint on an interval. It only activates if the WS client fails to connect within 30 seconds of startup.
## Live Gateway Connection
### Startup Sequence
1. Both WS client and REST client start concurrently
2. REST client waits 30s for WS readiness signal (`wsReady` channel)
3. If WS connects successfully → REST client stands down (logs "using WS — REST poller standing down")
4. If WS fails within 30s → REST client falls back to polling (logs "WS not ready — falling back to REST polling")
5. If no WS client configured → REST client polls immediately
### WebSocket Client (Primary)
- Config: `WS_GATEWAY_URL` (default: `ws://host.docker.internal:18789/`), `OPENCLAW_GATEWAY_TOKEN`
- Protocol: v3 handshake (challenge → connect → hello-ok)
- Initial sync: `agents.list` + `sessions.list` RPCs → persist → merge → broadcast `fleet.update`
- Live events: `sessions.changed`, `presence`, `agent.config`
- Reconnection: exponential backoff (1s → 2s → 4s → ... → 30s max)
### REST Poller (Fallback)
- Config: `GATEWAY_URL` (default: `http://host.docker.internal:18789/api/agents`), `GATEWAY_POLL_INTERVAL` (default: 5s)
- Only used when WS is unavailable
- Polls the `/api/agents` endpoint and syncs agent status changes
### Wiring
```
main.go
├── wsClient = NewWSClient(...)
├── restClient = NewClient(...)
├── wsClient.SetRESTClient(restClient) // WS notifies REST on ready
├── restClient.SetWSClient(wsClient) // REST defers to WS
├── go wsClient.Start(ctx) // primary
└── go restClient.Start(ctx) // fallback (waits for WS)
```
## Key Design Decisions
- **Push over poll**: WS is preferred for real-time updates; REST is a safety net
- **DB first, then SSE**: All event handlers persist to DB before broadcasting
- **Graceful degradation**: System works without WS; REST provides basic functionality
- **No hard dependency on REST /api/agents**: If WS is connected, REST endpoint is never called
