Bug: Button Component Has Glitchy Animation

## Environment

* Platform: **iOS 26.1**
* Framework: **React Native**
* Device: iPhone (physical & simulator)
* Affected Component: `Button`

## Description

The button component exhibits a **glitchy / jittery animation** on iOS 26.1 during press or interaction.
Animations appear to stutter, snap, or replay unexpectedly, resulting in a poor user experience.

This issue seems platform-specific to iOS.

## Steps to Reproduce

1. Run the app on iOS 26.1
2. Navigate to any screen with a button
3. Press or rapidly tap the button
4. Observe the animation behavior

## Expected Behavior

* Smooth and stable press animations
* Consistent transition timing

## Actual Behavior

* Glitchy, jittery, or snapping animation during interaction

## Reproducible Demo

N/A (reproducible in the app)

首先，在 App 中重現 iOS 26.1 上的 Button 動畫，並在實體裝置或模擬器上同時使用按壓和快速點擊進行測試。追蹤 Button 元件的按壓動畫行為，並將其與預期的轉場時序進行比較。當互動流暢、穩定，且不會意外跳變、卡頓或重播時，即表示完成。
