/**
 * Patch @uswriting/exiftool@1.0.9 after install.
 *
 * Problem: parseMetadata / writeMetadata fail when ExifTool prints warnings to stderr
 * even if exit code is 0 (no stdout / no strip bytes returned).
 *
 * Fix: remove the two stderr early-return checks in the published bundle.
 * Upload safety still relies on post-strip re-read + isCleanAfterStrip (app code).
 *
 * Upstream: https://github.com/6over3/exiftool (issue: warnings incorrectly treated as errors)
 *
 * Re-verify when bumping @uswriting/exiftool: search dist for these exact snippets.
