Summary

This PR introduces native support for bitwise operations in Laravel's Query Builder and Eloquent ORM. Currently, developers need to use whereRaw() for bitwise operations, which reduces code readability and type safety.

What does this PR do?

1. Adds new Query Builder methods:

   • whereBitwise() / orWhereBitwise() - Check if bits are set
   • whereNotBitwise() / orWhereNotBitwise() - Check if bits are not set
   • whereBitwiseExact() - Check for exact bit pattern match

2. Adds Eloquent Builder support:

   • All Query Builder bitwise methods available in Eloquent
   • Maintains consistency with existing Eloquent patterns

Breaking Changes

None. This PR only adds new functionality without modifying existing behavior.

Usage Examples

Basic Usage:

// Check if user has read permission (bit 4)
User::whereBitwise('permissions', 4)->get();

// Check multiple permissions with OR
User::whereBitwise('permissions', 4)
    ->orWhereBitwise('permissions', 2)
    ->get();

// Check users without delete permission
User::whereNotBitwise('permissions', 8)->get();

// Check exact permission set (all CRUD = 15)
User::whereBitwiseExact('permissions', 15, 15)->get();

Complex Queries:

User::where(function ($query) {
    $query->whereBitwise('permissions', 4)
          ->orWhereBitwise('permissions', 2);
})->whereNotBitwise('permissions', 8)->get();
