* [overleaf-editor-core] Restructure TextOperation hierachy Restructures the hierachy of TextOperations to include a superclass EditOperation. This superclass will later on contain other classes used for tracked changes and comments. * [overleaf-editor-core] Update json format of LazyStringFileData * [history-v1+project-history] Fix TextOperation.fromJSON calls * [overleaf-editor-core] Change EditOperationBuilder.fromRaw to fromJSON * [overleaf-editor-core] Update apply and invert functions to accept FileData * [overleaf-editor-core] Pass missing argument to store method * [overleaf-editor-core] Remove unused method * [overleaf-editor-core] User EditOperationTransformer * [overleaf-editor-core] Clean up JSDoc comments * [overleaf-editor-core] Add tests for EditOperation * [overleaf-editor-core] Update JSDoc types GitOrigin-RevId: 9c22a3a89b8483bdb87b43f329ddbdd887ffed42
