feat: display agent name alongside label in terminal title and list output

When a label is set (e.g. "bob"), the display becomes "bob (claude-implementer)"
so the agent type is always visible. Affects all three backends (docker,
macos-container, smolmachines) and the `cli.py list active` output.

Closes #243
