Add __isset() method to Request class for attribute existence check

[tusharnain]

Overview

This PR introduces the __isset() magic method to the Request class, enabling attribute existence checks similar to how __get() retrieves attributes.

Changes

• Added __isset(string $name): bool method to Request.php.
• Delegates existence checking to the base request() instance.

/**
 * Determine if an attribute exists on the base request.
 *
 * @param  string  $name
 */
public function __isset($name): bool
{
    return isset(request()->$name);
}

Benefits

• ✅ Provides a consistent way to check if a request attribute is set.
• ✅ Improves developer experience when working with dynamic request properties.
• ✅ Keeps behavior aligned with the existing __get() method.

Notes

• Backward compatible — no breaking changes introduced.
• Complements existing request property access patterns.
