* Generates a unified GitHub release body for a trigger.dev version release.
*
* Usage:
* node scripts/generate-github-release.mjs <version>
*
* Reads:
* - The enhanced changeset release PR body (via RELEASE_PR_BODY env var or stdin).
* By the time this runs, the PR body has already been enhanced by enhance-release-pr.mjs
* to include server changes, deduplication, and categorization. The .server-changes/ files
* themselves are already deleted (consumed on the release branch, same as .changeset/ files).
* - Git log for contributor info
*
* Outputs the formatted GitHub release body to stdout.
