refactor: use static motion elements and remove motionComponent prop

[Yeom-JinHo]

resolve #884

Description

This PR focuses on fixing react-hooks/static-components compatibility across text-related Magic UI components by removing render-time dynamic motion component creation.

Because stability and cross-project lint compatibility are the priority, this includes breaking API changes to keep behavior predictable and type-safe.

Changes

• Static Motion Components (major fix): Replaced motion.create(...) in render paths with static motionElements maps in:
  • TextAnimate
  • HyperText
  • LineShadowText
  • TypingAnimation
  • Terminal’s TypingAnimation
• as Typing (breaking change): Narrowed as from broad ElementType to a supported tag union (article | div | h1 | ... | span) for consistency and safer refs/types.
• Type Safety:
  • Updated relevant props to Omit<MotionProps, "children"> where needed.
  • Fixed ref typing in HyperText and TypingAnimation paths.
• TypingAnimation Behavior: Added state reset when source text input changes to avoid stale animation state.
• Docs + Registry Sync: Updated MDX docs and regenerated public/r/*.json + llms-full.txt to reflect API changes.

Motivation

• Ensure components are compatible with stricter React Hooks lint environments (static-components rule).
• Remove runtime component-creation risks and improve rendering stability.
• Standardize polymorphic behavior across components with a predictable, maintainable API surface.
• Keep generated registry/docs in sync so downstream consumers get accurate types and usage guidance.

Breaking Changes

• Narrowed as type to a fixed supported tag union in updated components.
  -> Passing arbitrary/custom component types is no longer supported via as.
• TypingAnimation now renders with an outer wrapper element for in-view tracking.
  -> Projects relying on exact DOM structure/selectors may need minor CSS adjustments.
