[implement] : Pre-commit Hook for Auto-formatting Solidity Files

[Nikuunj]

Description

Add a Git pre-commit hook to automatically format Solidity and related files before each commit.
The setup should run Prettier on staged files, re-stage the formatted changes, and block the commit if formatting fails. This ensures consistent code style and prevents unformatted code from being committed.

commit → auto-format → git add → commit
