DLC Pro native frequency scan

sweep.dlcpro_frequency

Triangle or sine scan with PI held. Optional center lock uses complete, time-weighted optical cycles; inadequate coverage produces no correction. TEC follows the scan center. The full PZT and built-in current-feedforward envelope is checked by the owner. No buffered arbitrary waveform support is claimed.

Offline implementation only. Hardware operation requires commissioning and reviewed laser configuration. No production changes are included.
