Detailed Description

Undoable action for painting tiles on the overworld map.

Captures a batch of tile changes (from a single paint stroke or rectangle fill) with both old and new values so that Undo() and Redo() are fully self-contained.

Consecutive paint actions on the same map within kMergeWindowMs are merged into a single undo step via CanMergeWith/MergeWith.
