Domain-agnostic prefab editing for the Pajama Studio prefab framework.

Phase 1 — the headless core (this release):

• EditorOp — the complete, undoable editor vocabulary: select, transform, component/field edits, add/remove/rename entities.
• createEditorState / applyOp / undo / redo — a pure reducer with a bounded history; selection changes never pollute undo.
• usePrefabEditor(prefab, { store }) — React bindings with revision tracking and debounced autosave into any PrefabStore. The hook edits one root prefab today; package-aware stores wrap that root into a PrefabPackage so the same backend can later preserve nested dependencies.

Bring your own viewport: a gizmo emits setTransform, an outliner emits select, an inspector emits setComponentField — the core doesn't care what renders the scene. Domain packs contribute their own inspector sections keyed off their component vocabularies (see prefab-core's Agent Catalog for machine-readable block semantics).

Phase 2 adds reference DOM panels; phase 3 an optional R3F viewport.
