@flighthq/command

Undo/redo command history — commands are plain kind-tagged data (property set, add/remove/reorder child, composite) whose execute/undo/merge are free functions registered per kind in a keyed table and resolved at dispatch, with a stack tracking applied/redoable entries, per-kind merge coalescing for drag sequences, nestable transaction brackets that fold many commands into one entry, an optional maxSize cap, and an opt-in onChange signal; no closures on the stack, so entries stay inspectable data
