- Inline update logic (pull → compare digests → up -d → prune → notify)
- Inline backup logic with dynamic Postgres detection: any running
<stack>_db container is dumped using the <stack>/<stack> convention
- Systemd unit files are now generated on `install` from embedded
heredocs pointing at stacks.sh itself — no external scripts needed
- Root .env (WEBHOOK_URL, RESTIC_REPOSITORY, RESTIC_PASSWORD) replaces
the per-service .env files in _backup/ and _update/
- Remove _backup/ and _update/ directories entirely
- Update README accordingly
