docs: fix remote-workspaces-faq CLI commands and update staging doc

[technical-writer-agent] - remote-workspaces-faq.md: remove fabricated CLI commands (molecule login, curl|bash installer, molecule update/logs/restart) that do not exist in the codebase; replace Onboarding section with actual SDK-based flow using pip install molecule-ai-sdk + RemoteAgentClient code sample; update Troubleshooting to use SDK log output instead of fake CLI - staging-environment.md: update status from "Planned" to "In Progress"; document CI image pipeline (staging-<sha>, staging-latest) as live; note Railway/Neon/Vercel items are tracked in molecule-controlplane

-## Known Limitations
-
-### Playwright / browser system libs are not installed
-
-The base `molecule-ai-workspace-runtime` image (`workspace/Dockerfile`) is built on `python:3.11-slim` with Node.js 22, git, and `gh` — about 500 MB. It deliberately **does not** include the system libraries Chromium needs (`libnss3`, `libatk-bridge2.0-0`, `libxkbcommon0`, `libcups2`, `libdrm2`, `libxcomposite1`, `libxdamage1`, `libxrandr2`, `libgbm1`, `libpango-1.0-0`, `libasound2`, etc.). Adding them would inflate the image by ~200–250 MB (~40%) for every workspace, even though only frontend / QA workspaces ever launch a browser.
-
-Practical consequences:
-
- `npx playwright test` (and any other Chromium-driven E2E tooling) **will fail at browser launch** when run from inside an in-container workspace agent.
- The error surface is missing-shared-object messages such as `error while loading shared libraries: libnss3.so` or `Host system is missing dependencies to run browsers`.
- Unit and integration tests (Vitest, Jest, etc.) that don't spawn a real browser are unaffected.
-
-Recommended workflow:
-
-1. **Run E2E in CI**, not in-container. The Gitea Actions self-hosted runner (and the GitHub Actions runner used by mirror repos) has the full Playwright dep set installed and is the supported surface for E2E. Push a branch, let CI run the suite.
-2. **Local debugging** of a single failing spec is best done on a developer laptop with `npx playwright install-deps` run once.
-3. **In-container iteration** on test logic itself is fine — write specs, lint them, type-check them — just don't expect `playwright test` to actually launch a browser.
-
-If a particular workspace role genuinely needs in-container E2E (a dedicated QA template, for instance), the right place to layer Playwright deps is in a **role-specific adapter template image** that does `FROM molecule-ai-workspace-runtime:<tag>` and adds `RUN npx playwright install-deps`. Open a request against `molecule-ai-workspace-runtime` if you need this template stamped.

 **Q: How does the platform authenticate a remote workspace?**

-Remote workspaces authenticate with an org-scoped bearer token (not a personal token). The platform validates the token against the tenant and provisions a session-scoped credential for A2A communication. If the remote machine is revoked from the org, the token is invalidated and the workspace goes offline within one heartbeat cycle (~15s).
+Remote workspaces authenticate with a workspace-scoped bearer token. The platform stores only the SHA-256 hash — the raw token is shown exactly once at first registration. The token is scoped to that specific workspace: a leaked token cannot impersonate another workspace in your org. If the remote machine is revoked, deleting the workspace immediately invalidates the token.

 **Q: Can a remote workspace make outbound connections my firewall would block?**

-The agent only makes outbound HTTPS/WSS connections to the platform. It does not accept inbound connections. Your firewall only needs to allow `*.moleculesai.app` outbound — same as a browser.
+The SDK only makes outbound HTTPS calls to the platform. It does not accept inbound connections. Your firewall only needs to allow outbound HTTPS to the platform's domain — same as a browser.

 **Q: What happens to data if the remote workspace is disconnected or the machine is wiped?**

-Workspace state lives in the platform unless explicitly persisted. For remote workspaces, you can attach a Cloudflare Artifacts repo to snapshot state to disk on your own infrastructure. If the agent reconnects, it re-registers and Canvas picks up where it left off.
+Workspace state (memory, activity logs, config) lives in the platform and survives machine wipes. If the agent reconnects, it re-registers and Canvas picks up where it left off.

+
+client = RemoteAgentClient(

+)
+client.register()           # issues + caches bearer token
+secrets = client.pull_secrets()   # fetch workspace secrets
+print("Secrets:", list(secrets.keys()))
+
+# Heartbeat loop — keeps workspace visible on Canvas
+client.run_heartbeat_loop()

 **Q: Can I use my existing SSH keys and git config with a remote workspace?**

-Yes. The remote runtime does not virtualize or override your shell environment. SSH keys, git config, dotfiles — all persist across sessions and are available to the agent.

+**Q: How do I update the remote agent when a new SDK version ships?**

-`molecule update` — pulls the latest agent binary from the platform, does a rolling restart. Zero downtime if the agent reconnects within the heartbeat window.
+```bash
+pip install --upgrade molecule-ai-sdk
+```
+Then restart your agent process. Zero downtime if the agent reconnects within the heartbeat window (~30s).

 **Q: What's the latency like for A2A coordination between a remote workspace and a container workspace?**

-A2A messages route through the platform's relay, so latency is essentially internet RTT between the remote machine and the platform's edge (~20–80ms depending on geography). For comparison, container workspaces on-platform have <5ms RTT. The practical difference for most coordination patterns is imperceptible.

For comparison, container workspaces on-platform have <5ms RTT. The practical difference for most coordination patterns is imperceptible.

 **Q: Can I run a remote workspace on a machine that's behind NAT with no public IP?**

-Yes. The agent initiates the outbound WebSocket connection to the platform — no inbound ports needed. This is the primary design reason remote workspaces use WSS rather than HTTP.
+Yes. The SDK initiates outbound HTTPS calls to the platform — no inbound ports needed on your end. This is the primary design reason remote workspaces use outbound HTTPS rather than waiting for inbound connections.

 **Q: Remote workspace shows offline in Canvas but the process is running on my machine.**

-1. Check the agent log: `molecule logs --workspace my-agent`
-2. Confirm the machine has outbound internet access: `curl -s https://[your-org].moleculesai.app/health`
-3. Check token validity: `molecule auth status` — re-authenticate if expired
-4. Restart the agent: `molecule restart --workspace my-agent`
+1. Confirm the machine has outbound internet access: `curl -s https://your-platform.example.com/health`
+2. Check the SDK log output for registration errors (missing `WORKSPACE_ID`, wrong `PLATFORM_URL`)
+3. Verify the bearer token is valid — re-register with `client.register()` to confirm
+4. Check network path: `curl -v -X POST https://your-platform.example.com/registry/heartbeat` with the token

 **Q: A2A messages to my remote workspace are timing out.**

-Remote workspaces must maintain the outbound WebSocket connection. If the machine sleeps or loses connectivity, the connection drops and A2A messages queue for up to 5 minutes before failing. The agent will re-register on reconnect — Canvas will show it back online.
+The agent must call `/registry/heartbeat` every 30 seconds to stay online. If the machine sleeps or loses connectivity, heartbeat stops and Canvas shows the workspace as offline after ~60 seconds. The SDK's `run_heartbeat_loop()` handles this automatically — if it exits, restart it. On reconnect, the agent re-registers and Canvas returns to online.

 **Q: My remote workspace is online but can't reach internal APIs.**

-The remote runtime does not inherit VPN credentials from the machine by default. If internal APIs require VPN, you'll need to either configure the VPN on the host machine outside the agent, or use the platform's `/cp/*` reverse proxy for same-origin access (same-origin-canvas-fetches.md).
+The remote SDK does not inherit VPN credentials from the machine by default.
