feat: add useScrollTrigger, useTransform, useEffectEvent (port of #11)#13
Merged
Conversation
Port the scroll hooks from Clément Roche's #11 onto the packages/hamo structure: - useEffectEvent: promote the stable-callback helper to a public hook; use-debounce now consumes it (removes the private useStableCallback duplicate). - useTransform / TransformProvider: context-based transform accumulation for parallax compensation. Zero dependencies. - useScrollTrigger + Debugger: scroll-progress tracking with GSAP-style position syntax, optional Lenis integration (graceful native-scroll fallback), exposed with the debug overlay behind the hamo/scroll-trigger/debugger subpath. lenis is an optional peer dependency; the debug store's emitter is inlined so hamo keeps zero runtime dependencies. Playground gains a /scroll-trigger demo. Co-Authored-By: Clément Roche <rchclement@gmail.com>

What this does
Brings Clément Roche's scroll hooks (#11) into the v1
packages/hamolibrary: useScrollTrigger (scroll-progress tracking for scrollytelling), useTransform / TransformProvider (parallax), and a public useEffectEvent. They were stranded on a branch built against the old repo layout; this re-applies them to the restructured monorepo so they ship with v1.Summary
