# Gitea Act Runner - Configuration and Registration
# =============================================================================
#
# Deploys the runner configuration and registers with Gitea.
# Registration is idempotent: only runs if .runner file doesn't exist.
#
# The .runner file contains the runner's identity after registration.
# DO NOT DELETE this file or re-registration will be required.
