def detect_app_name
  # Check any environment tfvars for the app_name
  Dir.glob('infrastructure/*/terraform.tfvars').each do |f|
    content = File.read(f)
    match = content.match(/app_name\s*=\s*"([^"]+)"/)
    return match[1] if match
  end

  # Check variables.tf for a default app_name value
  name = detect_app_name_from_variables_tf
  return name if name

  # Fall back to directory name
  File.basename(Dir.pwd)
end

#detect_environments ⇒ Object

Detects existing environments by scanning infrastructure/ directories. Each subdirectory with a main.tf is considered an environment.
