configuration.nix:
- systemd.services.opencode-web: one shared opencode server on 127.0.0.1:4096,
EnvironmentFile=/srv/cc-ci/.testenv (TINFOIL_API_KEY), ExecStartPre clears
stale /tmp/opencode so restarts never fail on the EEXIST race.
- services.nginx: reverse-proxy oc.commoninternet.net → localhost:4096,
bound to tailscale IP 100.84.190.30 (tailnet-only, plain HTTP).
DNS: A record oc.commoninternet.net → 100.84.190.30 (operator step).
launch.sh + launch-upgrader.sh:
- Drop per-session ports / OPENCODE_HOST; add OPENCODE_SERVER=http://127.0.0.1:4096.
- opencode backend: agents use `opencode run --attach $OPENCODE_SERVER --title $session`
so each shows up as a named session in the web UI.
