/**
 * Host-Integration SDK — the published public surface (ADR-1239 Phase E / #1683).
 *
 * External host-plugin authors import ONLY from this entry. It IS the contract:
 * everything it re-exports is public + versioned (PROTOCOL_VERSION governs the
 * set); everything else in gsd-core is internal. An SDK smoke test
 * (tests/sdk-smoke.test.cjs) builds a new host-plugin against this surface only
 * — proving an external author can wire a host without reading gsd-core internals.
 *
 * Surface: the negotiated schema + classification, the five adapters
 * (declarative/imperative/model/hook/state), and the serialized handshake.
 * Frozen so the public shape cannot be mutated by consumers.
