Hi there, thanks for your great work 🌟

Changes:

• Moved readline-ext from suggest to require, because that's a required ext. 😄
• Preferred php 8 functions, for example replaces substr with str_starts_with when needed.
• Moved Assests to autoload-dev, because I will not like to have Assests namespace in my production environment.
• Removed redundant variables & arguments.

I am open to receive your comments ✌️
