Combat overhaul: charge/gore, bear ram, matador taunt reactions

Bull charge damage:
- Tunnel-proof swept detection (prev→now segment) for matador gore and bear
  ram, so a 66 m/s dash no longer skips clean over the thin HitArea.
- Horns-first cone (bull_gore_arc): running into an enemy only wounds it when
  charging roughly at it, not a sideways brush.
- Dash is a committed lunge: bypasses the horns cone AND the survival roll, so a
  dash connect is a guaranteed kill. Cruise charges keep a speed-scaled roll
  (mat_charge_pierce). Roll ability defers to its own pop (is_rolling guard).

Bear:
- Horns-first swept ram detection (edge-triggered: one charge = one wound);
  a tunnelling or point-blank charge now lands where body_entered wouldn't.
- Overhead smash lane extends faster (0.1s) and further (20 m).
- Leap slam launches the bull from anywhere in the circle (ring_frac 0).
- Removed stray-quote syntax errors that broke the script.

Matador:
- Collider-driven stab (BladeHitbox) with recovery beat + taunt-after-hit so it
  stops machine-gunning the bull.
- A taunting matador answers a charge: spear from range, sword up close.

Spear projectile masks the BULL layer so throws connect.

Tests: matador_charge/stab/spear/taunt_react, bear_ram/hitbox/fx (+ unified
_fake_bull stand-in). Trimmed verbose comments.

Note: bear claw-emitter/death work is still WIP (3 bear_boss_test failures).
