GX Framework

Runtime mounting

GX can render without a runtime. Mounting is for the hosts that need stateful interaction, rerenders, and bridge code around a component tree.

Mount APIs

`gxwasm.Mount`	Mounts a root function into a host selector.
`gxwasm.MountApp`	Mounts a stateful app root.
`Handle.RequestUpdate`	Requests a rerender for one mounted root.
`Handle.Unmount`	Disposes one mounted root.

Boundary

Runtime bridges do not own provider calls, secrets, storage, authorization, or product policy. Hosts provide those pieces explicitly, while GX keeps the tree and callbacks reviewable.
