JSON schema generation now handles `Literal` types, ensuring that agents and tools using constrained value sets produce valid, complete schemas. This closes a gap that could cause schema generation to fail or produce incomplete type definitions for structured outputs.

Details:

- `Literal` types are now correctly represented in generated JSON schemas
- Improves reliability of structured output validation and tool definitions
- No migration required
