* Add output schema support for OpenAPI tools
Implement automatic output schema extraction from OpenAPI responses for
FastMCP tools, addressing issue #1070. Tools generated from OpenAPI specs
now have meaningful output schemas instead of null, improving agent
efficiency when working with structured API responses.
- Add extract_output_schema_from_responses() function to parse response schemas
- Enhance OpenAPITool to accept and use output schemas with proper wrapping
- Automatically wrap non-object responses to comply with MCP requirements
- Include schema definitions and compress unused ones
- Add comprehensive test suite covering object, array, and primitive responses
- Update existing tests to handle structured output with proper typing
- Maintain backward compatibility for specs without response schemas

* Move output schema tests to dedicated test file
Reorganize output schema tests into test_openapi_output_schemas.py to keep
the main test_openapi.py file focused and smaller, as requested. Added two
additional tests for schema definitions handling.
- Move all extract_output_schema_from_responses() tests to new file
- Add tests for schema definitions inclusion
- Remove output schema imports from main test file
