Feat: disableImagePasting Prop

[divyanshu-patil]

Description

This PR introduces a new prop, disableImagePasting, that allows consumers to prevent users from pasting images into the text input.

When enabled, image content from the system clipboard is blocked, ensuring the input accepts text-only content.

Issue

Closes: #31

Behavior Overview

iOS

• When disableImagePasting={true}:
  • Image pasting is completely disabled
  • The Paste option does not appear in the context menu when the clipboard contains only images
  • Text pasting continues to work as expected
• Behavior aligns with native iOS applications (Notes, Messages, WhatsApp)

Android

• When disableImagePasting={true}:
  • Sticker and GIF options are disabled
  • Image paste handling is blocked at the input level
  • ⚠️ The Paste option may still be visible in the context menu due to Android framework limitations
    • Android does not provide a reliable API to conditionally hide the Paste action based on clipboard content

What This Solves

• Improves UX consistency across controlled editors
• Avoids unexpected attachment uploads

Use Cases

• Command or terminal-style inputs
• Markdown or code editors that only accept text
• Form fields (comments, feedback, reports) that disallow media
• Enterprise or moderation-restricted applications
• Search bars and single-line text inputs
• subscription plans based image pasting
