CUB-200 : sync CI workflows with dev branch

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

-# 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
