Feature request: custom display names for agents (override folder name)

Love the office. One thing I kept wanting: the label under a character is the workspace folder name, but when running several long-lived Claude Code sessions in the same repo (an orchestrator plus helper sessions), they all show the same folder label.

It would be great to give agents custom display names — e.g. a mapping file (folder or session → name) in ~/.pixel-agents/, or a rename affordance on the agent card.

For now I patched dist/cli.js locally to read a names.json mapping folder names to display names, which works fine — happy to share details if useful.

Thanks for the great tool!
