/**
 * The node-only recursive source walker `/legibility` and `/theme-contract`
 * both need: collect scannable files under a directory, skipping vendor and
 * generated output. Extracted here because it drifted into two copies one day
 * apart with different skip lists — `/theme-contract`'s was missing
 * `.react-router` / `.wrangler` / `.turbo`, so it descended into and linted
 * framework-generated output the newer list correctly skips.
 *
 * Zero dependencies beyond `node:fs`/`node:path`, so either subpath can import
 * it without pulling in the other's unrelated surface (`/legibility`'s own
 * hand-written lexer, in particular).

/**

 * here, since which files count as "source" is a per-checker policy.
