Summary

Added internal hostnames so the Agents SDK browser can preview dev servers via private hostnames (e.g., preview.internal) without public exposure.
Simplified browserTool: it now runs model code in its own Dynamic Worker and no longer requires a CodemodeRuntime export.
Introduced target schemas for hosts, allowing the model to select ports or folders and persist selections across sessions.
