Subject: [PATCH] fix: replace deprecated util.isArray with Array.isArray

Replaced usage of `util.isArray()` with the modern `Array.isArray()` in flash.js to resolve Node.js deprecation warning [DEP0044].

- Removed import of `util.isArray`
- Updated conditional check to use `Array.isArray(msg)` instead
- Added inline comment to clarify the change

This update ensures compatibility with current and future versions of Node.js and eliminates the runtime warning.
