Add pkgs.uv to systemd.services.hermes-agent.path so that CronJobs
and terminal sessions can execute PEP 723 scripts via 'uv run'
(e.g. garmin-daily.py for Garmin Connect health data).
Also adds uv to environment.systemPackages for general availability.
- Delete home/features.old/ (archived old flat feature modules)

matrix-nio is installed in the container's writable venv layer
(~/.venv) but the hermes process uses the read-only Nix store Python.
This adds PYTHONPATH and LD_LIBRARY_PATH as container-level env vars
so matrix-nio + libolm (e2e encryption) are importable.
