/**
 * Print ONE version's section from CHANGELOG.md — the body for that version's
 * GitHub Release.
 *
 * Why this exists: the release workflow used `generate_release_notes: true` and
 * nothing else, which asks GitHub to synthesise "What's Changed" from a previous
 * release IT picks. With releases cut back-to-back (and prereleases interleaved)
 * that base is frequently far older than the previous version, so a release whose
 * changelog entry is a single line shipped ~13,600 characters listing every PR
 * across many versions. The reader cannot tell what actually changed in the thing
 * they just installed, which is the only question a release page has to answer.
 *
 * CHANGELOG.md is already curated per version (Keep a Changelog), so it is the
 * honest source: it says what changed, in our words, for exactly this version.
 *
 * Usage:  node scripts/changelog-section.mjs 0.50.31 [--file CHANGELOG.md]
 * Exits non-zero (and prints nothing to stdout) when the section is absent, so a
 * caller can fall back rather than publish an empty release body.
