# OpenCode GitHub/GitLab Setup Helper
#
# DESCRIPTION:
#   Detects git remote type (GitHub, GitLab, Gitea, Bitbucket) and checks
#   OpenCode integration status. Provides setup instructions and can create
#   GitHub Actions workflow files for OpenCode automation.
#
# USAGE:
#   opencode-github-setup-helper.sh <command>
#
# COMMANDS:
#   check           - Check OpenCode integration status for current repo
#   setup           - Show setup instructions for detected platform
#   create-workflow - Create GitHub Actions workflow file (GitHub only)
#   create-secure   - Create security-hardened workflow (recommended)
#   create-labels   - Create required labels for secure workflow
#   help            - Show help message
#
# EXAMPLES:
#   opencode-github-setup-helper.sh check
#   opencode-github-setup-helper.sh setup
#   opencode-github-setup-helper.sh create-workflow
#   opencode-github-setup-helper.sh create-secure
#   opencode-github-setup-helper.sh create-labels
#
# DEPENDENCIES:
#   - git (required)
#   - gh (GitHub CLI, optional but recommended)
