Format-preserving printer loses parentheses around BooleanNot expressions

Environment

• PHP-Parser Version: 5.6.1
• PHP Version: 8.4.4
• Reproducer: https://github.com/nikic/PHP-Parser/pull/1120

Description

When I wrap a BinaryOp\BooleanAnd node in a BooleanNot node, the format-preserving printer loses the required parentheses around the boolean AND expression. This produces semantically incorrect code.

Expected Behavior

The format-preserving printer should add parentheses around the wrapped expression:

$var = !(a() && b());

Actual Behavior

The parentheses are missing, changing the code's meaning:

$var = !a() && b();

Mutation

$stmts[0]->expr->expr = new \PhpParser\Node\Expr\BooleanNot($booleanAnd);
