sl-firmware 3e60d7552a feat: Battery voltage telemetry and LVC (Issue #613) ...

- Add include/lvc.h + src/lvc.c: 3-stage low voltage cutoff state machine
  WARNING  21.0V: MELODY_LOW_BATTERY buzzer, full motor power
  CRITICAL 19.8V: double-beep every 10s, 50% motor power scaling
  CUTOFF   18.6V: MELODY_ERROR one-shot, motors disabled + latched
  200mV hysteresis on recovery; CUTOFF latched until reboot
- Add JLINK_TLM_LVC (0x8B, 4 bytes): voltage_mv, percent, protection_state
  jlink_send_lvc_tlm() frame encoder in jlink.c
- Wire into main.c:
  lvc_init() at startup; lvc_tick() each 1kHz loop tick
  lvc_is_cutoff() triggers safety_arm_cancel + balance_disarm + motor_driver_estop
  lvc_get_power_scale() applied to ESC speed command (100/50/0%)
  1Hz JLINK_TLM_LVC telemetry with fuel-gauge percent field
- Add LVC thresholds to config.h (LVC_WARNING/CRITICAL/CUTOFF/HYSTERESIS_MV)
