fix(docker): use HEAD probe so SSE heartbeat doesn't time out healthcheck#1182

…heck `/api/heartbeat` is a `text/event-stream` endpoint that keeps the connection open and streams events. `curl -fsS` reads until the body ends, which never happens, so every probe hits the 5s timeout and Docker marks the server unhealthy — which in turn blocks `gitnexus-web` from starting via `condition: service_healthy`. Switch to `curl -fsSI` (HEAD): the server still returns 200 instantly, but there's no body to read so curl exits cleanly. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Bug:
docker compose up -dfails with dependency failed to start: container gitnexus-server is unhealthy even though the server is running and serving requests.Root cause: the compose healthcheck uses
curl -fsS http://localhost:4747/api/heartbeat, but that endpoint returns Content-Type: text/event-stream and keeps the connection open indefinitely. The 200 status arrives instantly, but curl reads until the body ends — which it never does — so every probe trips the 5s timeout and Docker marks the container unhealthy. gitnexus-web then refuses to start because of its condition: service_healthy dependency.Fix: switch the probe to
curl -fsSI (HEAD). Same 200, no body, curl exits cleanly. Verified locally: gitnexus-server reports healthy and gitnexus-web starts.
