Merge pull request 'SEV-337: add shared animations.css' (#7) from sev-337/shared-animations into main

Centralizes the animation primitives duplicated across public/vendor/admin
style.css — shimmer/.skeleton/.ai-shimmer, fadeIn/.fade-in, fadeInUp/.fade-in-up,
stagger delays, shake/.shake — as a plain-CSS export each app can import
(@switchev/web-shared/animations.css). Bumps to 0.6.0.
