map semantic refactoring kinds to specific LSP code action kinds

[loveucifer]

Summary

fixes #2382

Maps SourceKit semantic refactoring action strings to specific LSP CodeActionKind values instead of using the generic refactor kind. This enables standard refactoring keybindings and code action filtering to work properly for Swift.

Images After The Change

Changes

• Added lspKind computed property to SemanticRefactorCommand that maps:
  • Actions containing .extract. → refactor.extract
  • Actions containing .inline. → refactor.inline
  • Others → refactor (fallback)
• Updated retrieveRefactorCodeActions to use the new lspKind property

Haha, nice and simple scraping of the sourcekitd action ID. I like it 🙂

Should we also map .convert. to refactorRewrite and .move. to refactorExtract? Just looked through the list of sourcekitd refactorings in https://github.com/swiftlang/swift/blob/9b452820367ccc7b5d9effbc1565bcd945c81768/include/swift/Refactoring/RefactoringKinds.def#L21-L92.
