The implementation adds hover support to DocumentationLanguageService, which fetches symbol graphs from the primary language service and passes them through DocC for rendering. DocC naturally omits underscored attributes like @_spi, @_frozen, and @_alwaysEmitIntoClient from the declaration tokens, providing clean hover content without fragile string manipulation. Key changes: - Implement hover() in DocumentationLanguageService with full RenderNode to Markdown translation supporting declarations, abstracts, discussions, parameters, and return values - Register DocumentationLanguageService before SwiftLanguageService to prioritize DocC rendering when available - Maintain graceful fallback to SwiftLanguageService via requestNotImplemented for platforms without DocC - Remove obsolete XML filtering logic from SwiftLanguageService - Add test coverage for attribute filtering and parameter documentation - Delete UnderscoredAttributeFilteringTests as they tested the old approach This establishes the DocC infrastructure requested in #2213 and provides a foundation for future enhancements like markdown extension file support.
