Add natural disasters system

Introduce a natural-disasters feature: add DisasterManager, an abstract NaturalDisaster base class, and four concrete implementations (Earthquake, Meteor, Thunder, Tornado). Integrate the manager into SpeedHG (property, initialization/start) so disasters run on a timed cycle with guards for game state, grace period and per-disaster validation. Implementations: Meteor spawns a non-destructive LargeFireball impact, Earthquake applies nausea/impulses and particles, Thunder triggers multiple lightning strikes with fire chance, Tornado creates a particle vortex and pulls nearby players (uses a coroutine for precomputation). Add localization keys for disaster warnings in en_US.yml. Safety/cancel logic and flight/timeout cutoffs included to avoid leaks or invalid triggers.
