Enables "third-party developer tools" feature. This allows the inspected
web page to expose tools which provide debugging information to Chrome
DevTools for Agents.
Third-party developer tools enable web applications to expose internal
state, component hierarchies, or specific debug data that cannot be
deduced through static analysis. This allows Chrome DevTools for Agents
to provide richer, more actionable context to AI agents during debugging
sessions.
2 additional tools are enabled in Chrome DevTools for Agents for
interacting with third-party developer tools:
`list_3p_developer_tools()` and `execute_3p_developer_tool`.
Code changes in this PR:
- Rename "in-page tools" to "third-party developer tools"
- Unhide
- Make available in CLI
- Add documentation
