v0.1.0

• new StickyScrollTrigger(root): create one instance per container, then call the methods below on it
• createStickyTrigger: pin multiple scenes in sequence, sharing a single container, using nested position:sticky layers instead of GSAP's own pin
• createOverlapScroll: the effect where a lower section rises up and covers the section above it, without changing document height
• createStickyPin: pin badges and similar elements via plain position:sticky, entirely independent of GSAP's own pinning
• createResolvedTrigger / resolveScrollPosition: position-resolution APIs for using a plain ScrollTrigger effect inside the nested sticky structure
