dbmd-cli 0.2.4

//! Integration tests for `dbmd query`.
//!
//! `query` is a frontmatter filter resolved against the `index.jsonl` sidecar
//! (never a whole-store parse). The committed corpus-a sidecars are the
//! fixtures: `records/contacts/index.jsonl` holds four contacts, etc. Tests
//! assert the matched path set and the returned record fields, plus the flag
//! semantics (`--type`, `--where`, `--in`, `--limit`).
