Adds Browser Use as a shipped agent, as agreed with @EdgarArakelyan in Slack.

Each turn runs agent.mjs once with @browser_use/pi. It drives a Browser Use Cloud browser, or any Chrome DevTools endpoint passed as cdp_url, and it gets the task env's MCP tools as <server>__<tool>. It calls the [model] endpoint as an OpenAI-compatible one, with LITELLM_EXTRA_HEADERS included, and a context's turns continue one conversation through a saved history file. It's two files, a2a_server.py (151 lines) and agent.mjs (77 lines), plus registration like letta-code.

Validator (agent-env a2a-agent put, local Docker, gpt-5.4-mini):

Pass	Not implemented
card, message/send, tasks/get, agent-config identity, role, system prompt, text input, MCP tool calls on mail, live trajectory, tool-call count	skills, snapshot, peers, install/v1, non-text input

Unit tests in tst/unit/agents/browser_use cover one turn, an early stop, a crash and a timeout kill (24 passed with the bundle and image tests). A cancel or timeout sends SIGTERM first, so the agent stops its cloud browser before it is killed; this was checked live (browser went from active to stopped). To use it, the registration needs BROWSER_USE_API_KEY.
