 * Product commands, and nothing else.

 * This used to register a parallel set of `browser_*` tools and append a paragraph to a
 * coding agent's system prompt. That is why the chat answered "what can you do?" like a
 * coding assistant: it was one, wearing a browser hat. The tools now come from
 * `composeAgent`, which is the same call the CLI and the suite make, and the system prompt
 * is replaced rather than extended.
 *
 * What stays here is genuinely the product's: starting and stopping a run, handing control
 * to the operator, approving knowledge. Those are lifecycle, not agent capability.
