 * Emit a logical operator expression as CSharpExpressionAst
 *
 * In TypeScript, || is used both for:
 * 1. Boolean OR (when operands are booleans)
 * 2. Nullish coalescing fallback (when left operand is nullable)
 *
 * In C#:
 * - || only works with booleans
 * - ?? is used for nullish coalescing
 *
 * We check if || is used with non-boolean operands and emit ?? instead.
