TernaryToNullsafeCoalesceRector can change the behavior of an expression when its fallback is another ternary:

// Before transformation:
return $object !== null ? $object->name : ($flag ? 'first' : 'second');

// Actual output before this fix:
return $object->name ?? $flag ? 'first' : 'second';

// Expected output:
return $object->name ?? ($flag ? 'first' : 'second');

When the object exists and its name is 'name', the original expression returns 'name', while the incorrect output returns 'first'. During format-preserving printing of a new Coalesce, the reused ternary operand loses its original parentheses.

Mark the right-hand ternary operand of a new Coalesce with the existing WRAPPED_IN_PARENTHESES attribute. This preserves the original nodes and formatting, including rules that already set this attribute themselves.

Add a regression fixture covering property access, a nullsafe method call, and a reversed comparison with null with a short ternary fallback. The fixture fails on the original main branch and passes with this change.

Validation on PHP 8.4: composer check-cs, composer phpstan, and the full vendor/bin/phpunit suite pass: 4,903 tests, 5,928 assertions, and one existing skipped test. All 26 focused rule and printer tests also pass.
