0.0.20.5 — Leap frequency + meteor shockwave collision safety

Patroller / Phayrector leap tuning:
- Preserve existing leap mechanics, height, targeting, navigation follow-up and cooldown structure.
- Patroller eligible-tick leap probability: 0.020 -> 0.012 (60% of prior frequency).
- Phayrector eligible-tick leap probability: 0.010 -> 0.006 by threshold 0.990 -> 0.994 (60% of prior frequency).

Meteor shockwave:
- Do not alter shockwave radius, timing, falloff, damage, impulse strength, vertical component,
  direction, particles, sounds, or the normal entity impulse.
- The prior ServerPlayer-only positional assist used a direct connection teleport and could cross
  collision shapes. Route that exact requested displacement through Entity.move first, then sync
  the collision-resolved position to the client.
- On helper failure, never use the unsafe teleport fallback; the normal shockwave impulse remains.
