Pull request overview

This PR adds SIGTERM signal handling for graceful shutdown of the Draco adapter server, resolving issue #143. The implementation allows the server to respond to SIGTERM signals (commonly sent by container orchestrators like Kubernetes) in addition to the existing Ctrl+C/SIGINT handling.

Changes:

  • Added Unix-specific signal handling imports (tokio::signal::unix)
  • Created a SIGTERM handler future that listens for terminate signals
  • Integrated SIGTERM handling into both execution branches (with and without health service)
