refactor(skills): move contrast + animation-map scripts into hyperframes skill

[jrusso1020]

What

Moves skills/hyperframes-animation-map/ and skills/hyperframes-contrast/ scripts into skills/hyperframes/scripts/, and removes the now-empty top-level skill directories.

Why

These two directories had scripts but no SKILL.md — they looked like broken/incomplete skills and wouldn't be installed by npx skills add. They're actually helper scripts invoked by the main hyperframes skill (SKILL.md already references them in the "Quality Checks" section). Moving them under skills/hyperframes/scripts/ makes them part of the skill they belong to, so they get installed alongside it.

How

• Moved skills/hyperframes-animation-map/scripts/animation-map.mjs → skills/hyperframes/scripts/animation-map.mjs
• Moved skills/hyperframes-contrast/scripts/contrast-report.mjs → skills/hyperframes/scripts/contrast-report.mjs
• Removed empty skills/hyperframes-animation-map/ and skills/hyperframes-contrast/ directories
• Updated path references in:
  • skills/hyperframes/SKILL.md (animation-map usage example)
  • skills/hyperframes/scripts/animation-map.mjs (usage comment)
  • skills/hyperframes/scripts/contrast-report.mjs (usage comment)
  • packages/cli/src/commands/contrast-audit.browser.js (keep-in-sync comment)

Test plan

• Verify grep -r "hyperframes-animation-map\|hyperframes-contrast" . --include="*.md" --include="*.mjs" --include="*.js" --include="*.ts" returns no results (excluding node_modules)
• Verify skills/hyperframes/scripts/ contains both scripts
• Verify skills/hyperframes/SKILL.md references the new path
• Documentation updated (if applicable)
