/**
 * mapBodies — apply a transform to every immediate statement body of a node,
 * returning a structurally-fresh copy with bodies replaced.
 *
 * Useful for AST passes that need to rewrite every block-bearing node
 * uniformly (lowering passes, instrumenting, scope analysis, …) without
 * hand-listing every body-bearing node type at every call site.
 *
 * The per-node-type body enumeration lives in `bodySlots` (bodySlots.ts) —
 * the same table `walkNodes` descends by — so a new node type registers its
 * bodies in one place and both read and rewrite pick it up.
 *
 * Shallow by design: only IMMEDIATE bodies are transformed. Callers that
 * want deep rewrites recurse inside their transform (see patternLowering's
 * `lowerBody`).
