Remove the Operator HUD layout

Display > HUD > Layout and the set_hud voice action now offer Tactical,

Share-link codes are append-only, so operator keeps its hudVariant code.
A link, scene or saved state that names it restores the default Tactical
layout. The voice schema pins keep their legacy digests by restoring the
retired value before comparing; the full-payload digest is re-derived.
