调研方向

This issue names no files or tests. Start by reading the kernel module API in blocked issue #28 and tracing the write pipeline's undo-snapshot/emit stage. Done means atomic batches, including dependency cascades, undo and redo together; stack state updates reactively; and removing the module lets its code tree-shake from the bundle.

What to build

Extract undo/redo into a proper module that wraps atomic write batches, not individual field mutations. A single user action (e.g. move event + cascaded dependent shifts) is undone as one step — not as a sequence of individual commits.

Acceptance criteria

  • `UndoRedoModule` plugs into the kernel via the module API (#28), hooking the `undo-snapshot/emit` stage of the write pipeline
  • `undo()` reverses the most recent atomic batch (all events in the batch revert together)
  • `redo()` re-applies a reversed batch
  • `canUndo()` / `canRedo()` reflect the current stack state reactively
  • A dependency cascade (move + N propagated dependents) is treated as one batch — one `undo()` call reverses it entirely
  • Removing the `UndoRedoModule` causes undo/redo code to tree-shake out of the bundle
