 * @name XML escaper for RSS payloads
 *
 * @description
 * Pure-string XML escaper used by every `<item>` field in `rss.xml`.
 * Preserves valid pre-encoded entities (`&amp;`, `&#39;`, `&lt;`, etc.)
 * by only escaping `&` when it is not already part of an entity.
 *
 * Round-6 split: extracted from `scripts/generate-rss.ts`.
