orca.tasks.run_image

Imaging pipeline with model subtraction and peeling.

Implements a complete imaging workflow including: - Calibration application (delay + bandpass) - Antenna flagging - TTCal peeling - WSClean imaging (dirty + phase-centered) - Source blanking and uvsub

This version includes split after uvsub for cleaner output.
