Split formatting logic from Reference classes into dedicated formatter classes: - ToolResultFormatter: Formats tool execution results into Content items - PromptResultFormatter: Formats prompt results into PromptMessage items - ResourceResultFormatter: Formats resource results into ResourceContents items This refactor: - Eliminates 122 lines of code duplication between ResourceReference and ResourceTemplateReference (identical formatting logic) - Improves code organization by separating formatting concerns from capability reference management - Makes formatters independently testable and reusable - Reduces Reference classes by ~450 lines while maintaining all functionality Changes: - Create src/Capability/Formatter/* with three formatter classes - Update Reference classes to delegate to formatters instead of inline logic - Add comprehensive test coverage for all formatter classes - All existing tests pass; no behavioral changes
