/**
 * Deterministic parser for workflow scripts.
 *
 * The workflow entry statement must be a literal `export const meta = { ... }`.
 * Runtime execution intentionally happens elsewhere; this parser only accepts a
 * JSON-like JavaScript object literal for metadata so metadata is side-effect free.
 *
 * Concepts adapted from michaelliv/pi-dynamic-workflows (MIT): literal metadata
 * gate before workflow execution and deterministic metadata parsing constraints.
