/**
 * A hook that provides clipboard copy functionality.
 *
 * This hook returns an observable containing the last copied text and a function
 * to copy text to the clipboard. It handles browser compatibility and provides
 * feedback on whether the copy operation was successful.
 *
 * @returns A tuple containing:
 *   - copiedText: An observable string containing the last copied text or null
 *   - copy: A function that copies text to the clipboard and returns a promise
 *           that resolves to true if successful, false otherwise
 *
 * @example
 * ```tsx
 * const [copiedText, copyToClipboard] = useCopyToClipboard()
 *
 * const handleCopy = async () => {
 *   const success = await copyToClipboard('Hello, world!')
 *   if (success) {
 *     console.log('Text copied successfully')
 *   }
 * }
 *
 * return (
 *   <div>
 *     <button onClick={handleCopy}>Copy Text</button>
 *     <p>Last copied: {copiedText}</p>
 *   </div>
 * )
 * ```
 *
