//! §11.6 integration test: SHARED-collection triggers.
//! A group-owned `shared = true` trigger watches the group's shared collection.
//! A write to that shared collection (by any subtree app) matches the shared
//! trigger via the OWNING-group match query; a per-app collection of the same
//! name does NOT match it, and the shared trigger does NOT match a per-app
//! write (the `shared` flag is the namespace boundary).
//!
//! Deterministic: drives `list_matching_shared_kv` + `list_matching_kv`
//! directly (no async dispatcher). Skips when `DATABASE_URL` is unset.
