Resolves

Resolves #329

Changes

Core Implementation

• Enhanced useCopyToClipboard to accept either a string or an object with multiple format properties (plain, html, markdown)

• Added proper fallback handling for browsers that don't support ClipboardItem

Type Definitions

• Added new ClipboardFormats type to index.d.ts with optional properties for different formats
• Updated function signature to accept string | ClipboardFormats

Benefits

• Applications can provide formatted content that preserves styling when pasted
• No breaking changes - fully backward compatible
• Better user experience with multiple paste format options
