Scheduling: cron-based group runs via a daemon thread (scheduler.py)
started at API startup. Schedules managed inline on the group edit form.
last_fired_at persisted before run to prevent double-fire on restart.
Requires croniter (added to requirements.txt); DB migration adds
last_fired_at column to schedule table.
Deploy: deploy.sh now creates the pipekit system user, chowns the repo,
builds the venv as pipekit, and installs/enables the systemd unit.
systemd/pipekit.service is now a production-ready unit (User=pipekit
uncommented). pipekit secrets set preserves existing file permissions
instead of resetting to 0600. Driver registration is now idempotent
(upsert via get_driver_by_name + update_driver).
Docs: CLAUDE.md and SPEC.md updated to reflect groups, scheduling,
scheduler-in-API-process architecture, TUI deferred (not dropped),
stop-on-failure tradeoff, jrunner as prerequisite, and deploy flow.
