When `gt sling <bead> <rig>` is used with a rig name as target, sling now
automatically spawns a fresh polecat and slings work to it. This provides
a simpler alternative to `gt spawn --issue <bead> <rig>` for quick dispatch.
Changes:
- Add IsRigName() helper to detect bare rig names
- Add SpawnPolecatForSling() for lightweight polecat creation
- Update sling to detect rig targets and auto-spawn
- Update help text for both sling and spawn to document behavior
Design: spawn and sling remain distinct commands with different purposes:
- sling: Light spawn with hook + nudge (quick dispatch)
- spawn: Full workflow with mol-polecat-work, mail, witness notification
