/**
 * resolver-yaml — a MINIMAL, deterministic YAML/JSON reader for the artifact resolver's $ref bundler.
 *
 * The guard package has no YAML dependency; the resolver only needs to parse the constrained YAML
 * that appears in OpenAPI/AsyncAPI contract docs (block mappings, flow mappings, quoted keys, scalar
 * values, and `$ref` strings) to inline external file refs into a deterministic JSON bundle (§4.3).
 * It is NOT a general YAML engine — anything outside the supported subset throws, and the resolver
 * turns that into a `parse_error` unresolved entry (never a fabricated document).
 *
 * Determinism: plain scalars are kept as raw strings (no lossy type coercion), so parse→serialize is
 * byte-stable per input.
