[FEATURE] Add ease-float animation utility for subtle floating motion

[dishamaurya081-create]

Feature Request

Add a new animation utility called ease-float that creates a smooth floating effect by moving an element slightly up and down in a continuous loop.

Motivation

Floating animations are commonly used for:

• Hero illustrations
• Feature icons
• CTA buttons
• Cards
• Decorative UI elements

This utility would align with EaseMotion CSS's animation-first philosophy and provide developers with a reusable micro-interaction without requiring custom keyframes.

Proposed API

<div class="ease-float">
  Floating Content
</div>
