- Introduced SwapManager for sidecar journaling of buffer mutations, with a safe recovery mechanism. - Added group undo/redo functionality, allowing atomic grouping of related edits. - Implemented `SwapRecorder` and integrated it as a callback interface for mutations. - Added unit tests for swap journaling (save/load/replay) and undo grouping. - Refactored undo to support group tracking and ID management. - Updated CMake to include the new tests and swap journaling logic.
