Description

Refined the gsap-framer-scroll-animation skill to align with repository documentation and architecture standards.

Summary of Changes:

• Restructured the skill to include a main SKILL.md entry point along with isolated, dedicated documentation references (references/framer.md and references/gsap.md).
• Renamed the reference directory to references to match project-wide conventions (e.g., web-coder structure).
• Updated Copilot prompt recipes and included deep API references for both Framer Motion (Motion v12) and GSAP ScrollTrigger.
• Implemented cross-references to the premium-frontend-ui skill for frontend creative philosophy, differentiating "how to animate" (this PR) from "when and why to animate."

• Normalized all text with project line-endings (fix-line-endings.sh script applied to ensure standard LF).
• Only modified files (SKILL.md and the two references/*.md files) alongside the auto-generated README.skills.md are present in this commit.
