Executes a command on a playground VM via SSH. Use when you need to run commands on a playground for testing, debugging, or verification.
Applies a scripted solution to a running challenge (single- or multi-VM) and verifies every non-helper task completes. Use to validate a .solution.sh / .solution-NN.sh end-to-end.

Stop the challenge $0.
labctl challenge stop $0
This stops the current solution attempt and its associated playground.
If the command fails but the challenge's playground is still running, force the teardown with labctl playground destroy <playground-id> (find the ID with labctl playground list --filter challenge=$0). NEVER use labctl playground stop — it only suspends the playground instead of terminating it.
