refactor(runtime): own combat and magic intent

Move attack build/repeat state, combat-mode policy, authoritative auto-target transitions, and spell-cast intent beneath RuntimeActionState. Keep App as the input, world-query, DAT-policy, transport, and presentation adapter while preserving retail request and busy ordering. Add direct/graphical parity, reset, failure, and instance-isolation coverage.
