Replace per-decky sniffer containers with a single host-side sniffer
that monitors all traffic on the MACVLAN interface. Runs as a background
task in the FastAPI lifespan alongside the collector, fully fault-isolated
so failures never crash the API.
- Add fleet_singleton flag to BaseService; sniffer marked as singleton
- Composer skips fleet_singleton services in compose generation
- Fleet builder excludes singletons from random service assignment
- Extract TLS fingerprinting engine from templates/sniffer/server.py
into decnet/sniffer/ package (parameterized for fleet-wide use)
- Sniffer worker maps packets to deckies via IP→name state mapping
- Original templates/sniffer/server.py preserved for future use
- Replace hardcoded ALL_SERVICE_NAMES=[5 services] in cli.py with
_all_service_names() pulling dynamically from the plugin registry;
randomize-services now draws from all 25 registered honeypots
- Add build_base field to DistroProfile: apt-compatible image for service
Dockerfiles (ubuntu22/ubuntu20/kali get their own; others fall back to
debian:bookworm-slim since Dockerfiles use apt-get)
- Add build_base to DeckyConfig; propagate from distro in _build_deckies
and _build_deckies_from_ini
- Inject BASE_IMAGE build arg in composer.py for every build-based service
so each decky's containers reflect its assigned distro
- Update all 21 service Dockerfiles: FROM debian:bookworm-slim →
ARG BASE_IMAGE=debian:bookworm-slim / FROM ${BASE_IMAGE}
- Add tests/test_cli_service_pool.py and tests/test_composer.py (306 total)
