Update 0.35: DRS & ERS

Fassi Blue

New race systems

- Fully customizable DRS: add and edit DRS zones directly in the Circuit Editor (spline snap, wrap-around handling,

accurate zone length).

- Fully customizable ERS: new battery flow bar in race, configurable ERS modes (pace impact, deployment, recovery)

through the editor.

- Night racing & lighting: pick the time of day for each race and add lighting track by track.

- Weather visuals: new clouds and rain effects during races.

Dirty Air — full refactor

- Dirty air logic completely reworked.

- Choose the impact curve: linear / quadratic / cubic.

- All parameters are moddable — nothing hardcoded anymore.

- Fixed cascading effects between cars.

AI — new behavior

- Pace system rewritten with a probabilistic model (more variety, fewer robotic patterns).
