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. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
