fix(web-app,agent-presets): keep the goal service on the host plane

The Gateway serves the goal domain as Remote endpoints, and a Remote method
picks its receiver Service from a generated descriptor — `clear(agent, ref)`
takes its agent as a PARAMETER, so the invocation is direct and the receiver
resolves on the host. Behind the preset's entry-local realm there was nothing
to resolve, and every browser goal call answered `service-unavailable`: the
composer's Clear goal button left the bar on screen.

That is the `bash-env` criterion read from the other side. Injection is not the
only host relationship a Service can have; being READ from a host row is one
too. The registry is keyed by session, so one host instance serves every
session exactly as it did before presets. The preset keeps the model-facing
tool, which is the choice a preset is for.

Also reverts the cold-transcript presenter resolve: resuming an agent to reach
its presenters made the context meter drop its cache and token counts on every
cold-opened session, trading one silent degradation for another. The card
degradation it addressed is diagnosed and still open.
