/**
 * Smart AST pretty printer.
 *
 * Converts Dvala AST nodes (arrays) to readable source code.
 * Chooses idiomatic syntax regardless of how the AST was constructed.
 * Wraps lines at 80 columns (hard for structure, soft for atoms).
 *
 * Exposed as:
 * - TS function: `prettyPrint(node)` — for playground and tooling
 * - Dvala function: `let { prettyPrint } = import("ast")` — for in-language use
