//! `secrets::` SDK bridge integration tests — runs a real Rhai engine
//! against an in-memory `SecretsService` impl. Mirrors `sdk_kv.rs`: the
//! engine runs under `spawn_blocking` so the bridge's `block_on` has a
//! reachable runtime.
//!
//! This exercises the Rhai⇄JSON plumbing + the static `secrets` module
//! (set/get/delete/list, the missing→() contract, and the
//! String/Map/Array type round-trip). Encryption + authz + the
//! cross-app boundary are unit-tested at the service layer in
//! `manager-core::secrets_service`.
