Added Files:
src/syncterm/ripdiff.py
Log Message:
Add ripdiff.py for pixel-accurate RIPscrip rendering comparison

Compares DOSBox/RIPterm captures (640x350) against SyncTERM captures
(640x480) by upscaling the 350-row image using the same YCoCg-space interpolation algorithm SyncTERM uses internally (interpolate_height
from scale.c). Supports XWD and PNG input, EGA palette snapping, and per-channel threshold tolerance.
