Top-down shooter: TopDown decoupled move/aim (mouse/stick/move-dir/auto-aim),
a name-keyed Weapon registry (fire-rate/spread/pellets/pattern + data-driven
pierce/homing), and a self-contained deterministic Projectile pool with
faction-filtered Combat hits, pierce, ring/spiral patterns, and homing. One
weapon impl serves player + NPC via a want_fire intent. Budgeted wave Spawner.
Reuses ludic.gameplay Faction/Combat/Stats. 11-check example, in the suite.
