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
* Remove `getSummary` method and update descriptions in snapshots and code
* Add changelog entry
