Extends ValueDeserializer<FunctionToolCallOutput>

Custom deserializer for FunctionToolCallOutput.

The wire format written by FunctionToolCallOutputSerializer encodes output as a plain string (via Text.toString()). This deserializer wraps that string back into a Text instance.

Limitation: com.paragon.responses.spec.Image and com.paragon.responses.spec.File outputs are serialized via their toString() which is not reversible. Deserializing such outputs produces a Text wrapping the toString() representation — structurally safe but semantically lossy.
