autophotdir.py — One-click batch source detection + photometry

autophotdir.py v1.1 — One-click batch source detection + photometry.
Drop a directory of FITS images (HST, JWST, ground-based, etc.) → automatically detect sources with SEP, perform accurate aperture photometry using real background RMS, output a combined CSV catalog + diagnostic overlays.

Features
– Scientifically correct: uses measured background RMS for detection & errors
– Flexible aperture radius (--aper) and zero-point (--zp)
– Z-scale image display, per-image overlays (first 6), flux histogram
– Zero configuration beyond basics
