nugitea-daily.sh runs opencode with qwen3-coder over elixir_nugitea's
BACKLOG.md, one fresh session per task, and keeps a change only if it
stays in elixir_nugitea/, is under 800 lines and passes format, compile
and tests; then it commits and pushes agent/daily with its own deploy
key. opencode-agent.json denies git history, network, package and
service commands. Run by hand.
