The wave phase was k*speed(t)*t (its rate grows with session age: ~33 Hz noise
after 10 min) and its spatial term rotated about the world origin with the veer
(hundreds of rad/s at 9k yd from the first second). Now update_wind integrates
travel += speed*dt in f64 and publishes it wrapped at 4096 yd (wind_b.x); every
wave rate is a whole number of cycles per wrap, so the wrap is seamless. The
spatial term uses the fixed profile heading (wind_a.z); the veer and gust turn
only the bend. Capture offset WOW_CAPTURE_WIND_T for late-session shots.
