/**
 * Repairs the record links the success-story import wrote into RTE bodies:
 * it used t3://record?identifier=tx_vitec_download&uid=N (the TABLE name),
 * but the configured link handler key - and therefore the only identifier
 * config.recordLinks resolves - is `download`. Result: raw t3://record
 * hrefs leaked into the JSON payload ("Download Success Story" buttons,
 * found 2026-10-28).
 *
 * This migration rewrites identifier=tx_vitec_download -> identifier=download
 * in tt_content.bodytext (plain and &amp;-encoded variants). One-time,
 * idempotent, dry-run by default.
 *
 * Usage:  php migrations/fix_download_record_links.php          (dry run)
 *         php migrations/fix_download_record_links.php --apply
