Migration notes: godot-dialogue-system

Incremental upgrade for topics this skill covers. Apply one hop, stabilize/test, then next. Never skip hops.

If the project is < 4.0, follow godot-version-migration era bridges (legacy → 3→4) until 4.0, then these hops. Official 3→4: Upgrading from Godot 3 to Godot 4.
