Function decode_document_value

nodedb/src/data/executor/doc_format.rs:52–67

Convert a document byte blob to `nodedb_types::Value`. Preserves all native types (Geometry, DateTime, Decimal, etc.) that would be lost when decoding to `serde_json::Value`. Auto-detects msgpack vs JSON. Binary Tuple requires schema — callers should use `strict_format::binary_tuple_to_value` for strict collections.
