# job-cleanup.sh — sluit een per-job working tree af
#
# Usage: job-cleanup.sh <job_id>
#
# - Bewaart `git log` en `git diff` van de feature-branch in
#   /var/log/agent/jobs/<job_id>/  zodat je achteraf kunt zien wat de
#   agent heeft gedaan zonder de NAS-share met clones te vervuilen.
# - Verwijdert de working tree.
