feat(pixel-art): add hardware palettes and video animation (#12725)
Expand the pixel-art skill from 2 presets (arcade, snes) to 14 presets
with hardware-accurate palettes (NES, Game Boy, PICO-8, C64, Apple II,
MS Paint, CRT mono), plus a procedural video overlay pipeline.

Ported from Synero/pixel-art-studio (MIT). Full attribution in
ATTRIBUTION.md.

What's in:
- scripts/palettes.py — 28 named RGB palettes (hardware + artistic)
- scripts/pixel_art.py — 14 presets, named palette support, CLI
- scripts/pixel_art_video.py — 12 animation scenes (stars, rain,
  fireflies, snow, embers, lightning, etc.) → MP4/GIF via ffmpeg
- references/palettes.md — palette catalog
- SKILL.md — clarify-tool workflow (offer style, then optional scene)

What's out (intentional):
- Wu's quantizer (PIL's built-in quantize suffices)
- Sobel edge-aware downsample (scipy dep not worth it)
- Atkinson/Bayer dither (would need numpy reimpl)
- Pollinations text-to-image (Hermes uses image_generate instead)

Video pipeline uses subprocess.run with check=True (replaces os.system)
and tempfile.TemporaryDirectory (replaces manual cleanup).

Named Palettes

28 hardware-accurate and artistic palettes available to pixel_art(). Palette values are sourced from pixel-art-studio (MIT) — see ATTRIBUTION.md in the skill root.

Usage: pass the palette name as palette= or let a preset select it.

pixel_art("in.png", "out.png", preset="nes")           # preset selects NES
pixel_art("in.png", "out.png", preset="custom", palette="PICO_8", block=6)
