This commit introduces two key enhancements: the integration of Grafana Tempo for distributed tracing and the implementation of a dual-stack TCP listener for improved network compatibility.
- **Observability**:
- Adds the `tempo` service to the `docker-compose.yml` observability stack.
- Tempo is configured to collect and store traces, integrating with the existing OpenTelemetry setup.
- A custom `tempo-entrypoint.sh` script is included to manage volume permissions on startup.
- **Networking**:
- Modifies `http.rs` to support dual-stack (IPv4/IPv6) connections on a single socket.
- By setting the `IPV6_V6ONLY` socket option to `false`, the server can now accept both IPv6 and IPv4-mapped IPv6 traffic, enhancing cross-platform support.
