 * BRIEF: Create or overwrite a Gitea release with proper naming
 *
 * Usage:
 *   php release_create.php --version 09.01.00 --tag stable --token TOKEN --api-base URL
 *   php release_create.php --version 09.01.00 --tag development --token TOKEN --api-base URL --prerelease
 *   php release_create.php --version 09.01.00 --tag stable --token TOKEN --api-base URL --path . --repo MyRepo
 *
 * Replaces the inline bash in auto-release.yml Step 7b.
 * Detects extension metadata from manifest, builds a proper release name,
 * generates release notes, and creates (or overwrites) a Gitea release.
