Agents now ship with collector/prober/sniffer as systemd services; mutator, profiler, web, and API stay master-only (profiler rebuilds attacker profiles against the master DB — no per-host DB exists). Expand _EXCLUDES to drop the full decnet/web, decnet/mutator, decnet/profiler, and decnet_web trees from the enrollment bundle. Updater now calls _heal_path_symlink + _sync_systemd_units after rotation so fleets pick up new unit files and /usr/local/bin/decnet tracks the shared venv without a manual reinstall. daemon-reload runs once per update when any unit changed. Fix _service_registry matchers to accept systemd-style /usr/local/bin/decnet cmdlines (psutil returns a list — join to string before substring-checking) so agent-mode `decnet status` reports collector/prober/sniffer correctly.
