/**
 * Union truthiness emission for boolean conditions (AST-native).
 *
 * Handles the per-variant truthiness logic for union types:
 * - (T | null | undefined) nullable unions
 * - literal unions (e.g., "a" | "b")
 * - 2+ member compiler-owned runtime union carriers
 * - fallback for broad/object-like unions emitted as object
