📝 Walkthrough

Walkthrough

The Dockerfile is updated to use GHC version 9.6.7 instead of 9.6.6. UTF-8 locale configuration is added via two environment variables: LANG=C.UTF-8 and LC_ALL=C.UTF-8. The builder stage apt dependencies are extended to include the liburing-dev package alongside existing system packages. These changes affect the build environment configuration for the containerized Haskell toolchain.
