 * BRIEF: Bump version in manifest XML and CHANGELOG.md on a remote branch via Gitea API
 *
 * Usage:
 *   php version_bump_remote.php --path . --branch dev --bump minor --token TOKEN --api-base URL
 *   php version_bump_remote.php --path . --branch dev --bump patch --token TOKEN --api-base URL
 *   php version_bump_remote.php --path . --branch dev --bump minor --no-changelog --token TOKEN --api-base URL
 *
 * Options:
 *   --path         Repository root (reads current version from local manifest)
 *   --branch       Target branch to bump (required, e.g. dev)
 *   --bump         Bump type: patch | minor | major (default: minor)
 *   --token        Gitea API token (or GA_TOKEN env var)
 *   --api-base     Gitea API base URL for the repo
 *   --no-changelog Skip CHANGELOG.md bump
 *   --repo         Repository path (owner/repo) for API base construction
 *   --gitea-url    Gitea instance URL (default: env GITEA_URL)
