1. 1. Summary

The `remote_unittest` configuration applied `--run_under=//bazel:test_wrapper` to every Bazel command. When Evergreen invoked `bazel run //buildscripts:gather_failed_tests`, Bazel rejected the non-executable filegroup and failed to collect diagnostics.

This scopes the wrapper to `test:remote_unittest`, preserving wrapper behavior for `bazel test` while allowing reporting commands to run normally. Regression coverage was added for the configuration scope.
