Magnus Hedemark 612086170d feat: add post-processing script for analog print effects
Adds scripts/postprocess.py with 14 analog-print degradation effects
(warm grade, CRT scanlines, film grain, Bayer dither, vignette,
chromatic aberration, screen print texture, paper fiber, ink bleed,
palette compression, xerox threshold, registration offset, plate
wobble, print scuffs) and corresponding SKILL.md documentation.

Adapted from the approach pioneered by plntrprotocol/nous-branding
(MIT) — same goals, independent implementation.

Supports three modes: imprint (full 14 effects), nous (9 base effects),
standard (6 light effects). Intensity calibration from 0.45 to 0.8+.

Closes #33
