JSON-to-packed-document decomposition pipeline.

Decomposer walks a serde_json::Value tree depth-first, flattening nested objects into dot-separated field paths (e.g., address.city). Each leaf field is:

  1. Assigned a compact FieldId via the IdRegistry, creating the mapping on first encounter.
  2. Optionally dictionary-encoded through the collection’s ValueDictionary when the field’s observed cardinality is low and the value meets the minimum length threshold.
  3. Emitted as a FieldValue into a PackedDocBuilder.

Arrays and empty objects are stored as opaque JSON byte payloads (FieldValue::ArrayBytes) to preserve exact round-trip fidelity. Field names containing dots are rejected because dots serve as the path separator in the flattened schema.
