build: enforce frozen lockfile mode

This commit adds `lockfile_mode=error` to the `.bazelrc` file. This change ensures that any future builds will fail if the lock file is not up-to-date with the `BUILD.bazel` file, preventing inconsistencies and encouraging developers to commit updated lock files.
