Idea	Status	Tags	Summary
refactor_changes			On rename, move, or delete of files or symbols, the extension should update the idea index, import statements, embedded file references, comment references, and other idea references that are affected. The index should be resilient to duplication, particularly when ideas move between files: the old hosting file URI must be cleared before or when the destination is reindexed. [refactor_file_moves] [refactor_symbol_rename] [refactor_symbol_move] [refactor_symbol_delete] Implemented by ["../../packages/analytical/src/index-store/workspace-index.ts"], ["../../packages/extension/src/analytical_submodule/index-store/index-service.ts"], ["../../packages/language/src/reqlan-idea-refactor.ts"], and ["../../packages/extension/src/mutation_hooks_module/register-file-mutation-hooks.ts"].
refactor_symbol_delete			An idea declaration should offer a code action to delete it and update references. Deleting should remove the declaration, clear or rewrite AST and comment references that targeted it, and reindex affected files. [refactor_support] [refactor_changes] Implemented by ["../../packages/language/src/reqlan-idea-refactor.ts"], ["../../packages/language/src/reqlan-code-action-provider.ts"], and ["../../packages/extension/src/refactor_module/register-idea-refactor-commands.ts"].
