Playwright calls Emulation.setUserAgentOverride when creating a
browser context with a custom user agent. Without this handler,
Lightpanda returns UnknownMethod which crashes the Playwright
driver.
Add a noop handler matching the existing pattern for other
Emulation methods (setDeviceMetricsOverride, setEmulatedMedia, etc.)
so the CDP handshake can proceed.
Fixes#1436

This expands on the existing CDP node work used in DOM.search. It introduces
a node registry to track all nodes returned to the client and give lookups to
get a node from a Id or a *parser.node.
Eventually, the goal is to have the Registry emit the DOM.setChildNodes event
whenever necessary, as well as support many of the missing DOM actions.
Added tests to existing search handlers. Reworked search a little bit to avoid
some unnecessary allocations and to hook it into the registry.
The generated Node is currently incomplete. The parentId is missing, the
children are missing. Also, we still need to associate the v8 ObjectId to the
node.
Finally, I moved all action handlers into a nested "domain" folder.
