Feature/hw11 uart 2 - #11

…io controller (open, send start and drop signals)

…al via gpio

…d accelPath and attack speed, need to clarify it

… targets

- add DroneController module: converts mission decisions into UART CONTROL
  commands (accel + turnRate)
- steer toward the predicted target instead of the collapsing firePoint,
  removing the atan2 singularity at the drop moment
- guidance = pursuit (Kp*deltaAngle) + LOS-rate feed-forward (Kd*losRate,
  proportional navigation) to kill heading lag against maneuvering targets
- couple throttle to heading error: hold attackSpeed when aligned, coast while turning
- MissionProcessor: predict target over ammoFlightTime for both aiming (aimPoint)
  and the drop check, so the bomb leads a moving target
- expose aimPoint via MissionResult and wire DroneController into the main loop
- remove dead state-machine code carried over from earlier homework
