/**
 * Collects entity metadata from a Zod schema by walking its structure.
 *
 * Walks the schema once, detecting entity arrays (via `definitionRefRegistry`
 * annotations) and building metadata for each entity type including its
 * relative path from the parent entity (or root) and parent entity type linkage.
 *
 * Parent relationships are determined by `entityType.parentType` on the
 * `DefinitionEntityType` instance — when a parent type is set, the walker
 * finds the matching ancestor entity in its stack and computes the relative
 * path from there.
 *
 * Call once per schema and reuse the result.
