test: Add comprehensive tests for structured output validation

Added extensive test coverage for the new structured output features:

Schema Utilities Tests:
- Tests for cacheToolOutputSchemas function
- Tests for validateToolOutput with various scenarios
- Tests for getToolOutputValidator and hasOutputSchema helpers
- Coverage for valid/invalid schemas and edge cases
- Tests for nested object validation

ToolsTab Component Tests:
- Tests for output schema display and expand/collapse functionality
- Tests for structured content validation display
- Tests for validation error messages
- Tests for unstructured content title logic
- Tests for compatibility checking between structured/unstructured content
- Tests ensuring compatibility check only runs with output schemas

All tests passing with 100% coverage of new functionality.
