Builtin top-down Shooter controller (#60) — the source package **ludic.shooter**, conforming to the six-lever contract and built on the engine Body/Collider + ludic.gameplay Faction/Combat/Stats. `TopDown` decouples movement from aim (`aim_mode`: mouse / right-stick / move-direction / nearest-enemy auto-aim, with a `turn_rate` for tank-style rotation). Weapons are a name-keyed **registry** (`Weapon.def("shotgun", …)` — add a gun with zero code) with per-weapon fire-rate, damage, speed, spread, pellet count, pattern (single / spread cone / ring / spiral), plus data-driven pierce (`Weapon.set_pierce`) and homing (`Weapon.set_homing`); `esys_weapon` reads a `want_fire` intent so the **same** weapon fires for a player (input) and an NPC (AI). `Projectile` + `esys_projectile` is a self-contained deterministic pool: integrate, TTL, faction-filtered hit through `Combat.damage`, pierce, and homing that curves onto the nearest enemy — every step observable via `ProjectileSpawned` (mutable/veto) / `ProjectileHit` / `ProjectileExpired`. A budgeted `Spawner` wave director emits `SpawnRequested` / `WaveCleared`. Example: `examples/games/shooter_demo.ludic` (11 self-checks: movement, aim, faction damage, friendly-fire immunity, spread, kill, ring, homing, waves).
