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.
TLS-wrapped variant of the HTTP honeypot. Auto-generates a self-signed
certificate on startup if none is provided. Supports all the same persona
options (fake_app, server_header, custom_body, etc.) plus TLS_CERT,
TLS_KEY, and TLS_CN configuration.
