Adds docs for the Commands API (beta). It drives a session's browser over HTTP with commands such as snapshot, click, and fill. Merge once the endpoint shows up in the API reference.

Summary

• New overview/commands-api section:
  • Overview: quickstart, snapshots and refs, targets, retries, dialogs, and files.
  • Reference: every command, field, limit, and error code.
• Session Lifecycle and Configuration: Commands API requests now reset the inactivity timer.
• Files API: adds an upload command example.
• Steel Local vs Steel Cloud: adds ENABLE_COMMANDS_API.
• lib/agent-instructions.ts: adds the Commands API to /llms.txt and /AGENTS.md.

The examples use fetch and httpx until the SDKs ship sessions.commands.

Verification

• bun run lint, bun run spell, and bun run validate-links pass.
• The changed pages render on a local dev server.
