manage_browsers

Manage browser sessions on the Kernel platform. Created browsers run in isolated VMs and support headless/stealth modes, profiles, proxies, viewports, extensions, and SSH tunneling. Browser lifecycle lives here: create a session before running execute_playwright_code against it, and delete it when you’re done.

Actions

Action	Description
`create`	Launch a new browser session.
`list`	List existing sessions.
`get`	Retrieve details about a specific session.
`delete`	Terminate a session.
