Release 105

Spectral BLDC firmware V105 — reversed-wiring auto-calibration

#Cal now auto-detects reversed motor phase wiring during the open-loop spin and compensates it in software as a phase B<->C reflection, instead of failing and telling you to physically swap phases. Angle-offset calibration is now found automatically as part of #Cal itself (deterministic rotor-lock + verify + symmetry-sweep), so the standalone #Calangle command has been removed. #Info now reports the true firmware version instead of a stale EEPROM value. Existing calibrated units are unaffected and do not need #Default.
