The 'gt namepool' command was showing 'mad-max' for all rigs because
it created the pool with defaults instead of loading config. This made
it impossible to see if a rig had custom theme settings.
Load config before creating the pool, matching the logic in manager.go
that actually spawns polecats. Theme and CustomNames come from
settings/config.json, not from the state file.
