var crewSyncCmd = &cobra.Command{
	Use:   "sync",
	Short: "Create missing crew members from rigs.json config",
	Long: `Sync crew members from rigs.json configuration.

Creates any crew members defined in rigs.json that don't already exist locally.
This enables sharing crew configuration across machines.

Configuration in mayor/rigs.json:
  {
    "rigs": {
      "gastown": {
        "crew": {
          "theme": "mad-max",
          "members": ["diesel", "chrome", "nitro"]
        }
      }
    }
  }

Examples:
  gt crew sync                    # Sync crew in current rig
  gt crew sync --rig gastown      # Sync crew in specific rig
  gt crew sync --dry-run          # Show what would be created`,
