feat: Add title field support to MCP schema classes (#372)

Browse source 
- Add BaseMetadata interface with name() and title() methods for consistent metadata handling
- The Prompt, PromptArgument, Resource, ResourceTemplate, ResuorceLink, PromptReference, Tool,
  and Implementation classes implement the BaseMetadata interface, adding a new, optional title field
- Update constructors to support backward compatibility while allowing title specification
- Modify ResourceContent interface to extend BaseMetadata
- Update all test cases to accommodate new title parameter

The title field provides human-readable display names optimized for UI contexts,
while name remains for programmatic/logical use. This change maintains backward compatibility.
