feat(truapi-server): add platform runtime and host bridge

[pgherveou]

Adds the platform-facing truapi-server runtime and host bridge on top of the generated dispatcher plus the host logic and wire/chain layers. This PR wires platform callbacks, runtime state, WASM bindings, test support, and wire-boundary result-shape coverage.
