fix: Cast comparison values by attribute type in updateDocument

Cast individual values to their declared attribute type before
comparing with $old, skipping Operator instances. This normalizes
types degraded by cache JSON round-trips (e.g. float 1.0 → int 1)
without affecting the document that gets persisted.
