fix: Parse rig/name format in crew commands

All crew commands now accept "rig/name" syntax (e.g., "beads/emma")
in addition to requiring --rig flag. The rig is extracted from the
first path component.

Affected commands:
- gt crew at
- gt crew restart
- gt crew refresh
- gt crew remove
- gt crew rename
- gt crew status
- gt crew pristine
