Resolves issue where tools modified by mcp_component_fn were registered
with original names but accessible with modified names, causing "Unknown tool"
errors. Now tools are registered using their final modified names.

* Refactor Client session state with ClientSessionState dataclass

attributes, simplifying Client.new() and preventing concurrent proxy client
context mixing through client factory pattern.

* 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

Single-element lists like [1] were being incorrectly unwrapped to "1"
in unstructured content while multi-element lists remained as lists.
This created inconsistent behavior where the structure was lost for
single items.
This fix ensures lists always preserve their structure in unstructured
content regardless of length, making behavior consistent and predictable.
Also removes pretty-printing from JSON serialization for more compact
output across tools, prompts, and resources.

Adds test coverage for specific differences between OpenAPI 3.0 and 3.1 that can cause validation issues, including the scenario reported in GitHub issue #1021.
Test coverage includes:
- OpenAPI 3.0 boolean exclusiveMaximum format vs 3.1 numeric format
- OpenAPI 3.0 nullable vs 3.1 type array format
- Complex schemas with $defs and multiple exclusive constraints
- Edge cases with both exclusiveMaximum and exclusiveMinimum
These tests serve as regression prevention and document expected behavior for both OpenAPI versions.

Some Identity Providers use 'scp' claim instead of the standard 'scope' claim for OAuth scopes. This change updates the scope extraction logic to support both claims, with 'scope' taking precedence when both are present.
