"""validate — Check that the container is properly configured.

Python port of support/validate.

Run inside the container to verify:

- NOPASSWD sudo is configured

- Build tools are available

- Native modules (better-sqlite3) compile and load

- VSCodium server is accessible

- Pi CLI is functional

Usage: podman exec -it lpb-stack /opt/devstack/validate
