refactor: improve pre-commit hook to format only staged files

Changes:
- Format only staged PHP files (not all dirty files)
- Auto-stage only the files that were already staged
- Prevents accidentally staging unstaged changes
- Safer for partial staging workflows
- Maintains full automation for normal commits

This aligns with industry best practices from lint-staged
and prevents security risks from staging unintended files.

 ### `pre-commit` - Laravel Pint Auto-formatter ✅ ENFORCED
 **What it does:**
-- Runs Laravel Pint on staged files only (`--dirty`)
+- Runs Laravel Pint on staged PHP files only (not unstaged files)
 - Auto-formats code to match team standards
-- Automatically stages formatted files
