parked_ring_magazine_drain

Idea: Burn the magazine with a cheap leading decoy wave, hold every striker on a parking orbit just outside radar range, then release them all at once behind a thin decoy escort.

Weakness targeted: nearest_first commits interceptors and gun shots on range alone, with no regard for track class. Its result in the decoy_screen vs nearest_first pairing shows this: mean score_defender 0.107. In seed 0 it spent 13 of its 20 interceptors on 0.5-credit decoys, ended with stock_left 0, and was breached at tick 124.

This bot pushes that weakness further in four steps:

1. An opening wave of 20 decoys flies straight in. These are the only visible tracks, so nearest_first fires its whole magazine at them, two per tick, before any striker is seen.
2. Escort decoys and all strikers are steered onto an orbit at radius 470. That is outside the 450 radar range, so the defender cannot see them while it spends interceptors.
3. After the magazine has had time to drain, the escorts are released first and the strikers a few ticks later. Every striker then converges together from evenly spread bearings.
4. The escorts stay slightly closer to the asset than the strikers. A nearest-first gun spends its early shots on them, and the strikers arrive together, which overloads a gun that fires once per tick.

Bearings are assumed to be in radians.
