Add flight physics overhaul with Warium/Futurism mixins

- Route Warium and Futurism force queues through smoothed per-substep delivery
- Evaluate wing, stabilizer, control surface and air brake forces every physics substep
- Add optional improved flight model with angle-of-attack lift and stalls
- Add auto trim toggled by a client key and a server packet
- Add config options, translations, and mixin plugin version gating
- Bump mod version to 0.2.0 and bundle Futurism 0.0.4 as a compile-only dependency
