fix(neuron): surface full anyhow chain + ensure $HOME exists at start
Two fixes uncovered by the live validation against beast/benjy/quadbrat:

1. api.rs swallowed everything beyond the outermost anyhow context.
   The validation script reported '{"error":"fetch GGUF ...gguf"}' but
   the actual underlying hf-hub failure (cache dir creation, network,
   auth, etc.) was hidden. Switching every error response to
   format!("{e:#}") expands the full cause chain via anyhow's
   alternate Display format.

2. The neuron systemd unit declared the service user but never ensured
   /var/lib/neuron (its $HOME) existed. hf-hub defaults its cache to
   ~/.cache/huggingface/hub — when $HOME is absent the cache dir
   creation fails and the download aborts. Adding `StateDirectory=neuron`
   makes systemd create + chown that directory at activation; no spec
   change needed.
