The docker build contexts and syslog_bridge.py lived at repo root, which meant setuptools (include = ["decnet*"]) never shipped them. Agents installed via `pip install $RELEASE_DIR` got site-packages/decnet/** but no templates/, so every deploy blew up in deployer._sync_logging_helper with FileNotFoundError on templates/syslog_bridge.py. Move templates/ -> decnet/templates/ and declare it as setuptools package-data. Path resolutions in services/*.py and engine/deployer.py drop one .parent since templates now lives beside the code. Test fixtures, bandit exclude path, and coverage omit glob updated to match.
