[Bazel CI] Test Failure: Python Toolchain Regression - Windows Runtime Bootstrap Failures (Exit 2)

コミット 0f4ff60a1727300e1bace6233e566076736e9f15 の失敗を、USE_BAZEL_VERSION=f1be9ccfa5e5144f28e59686a03fd4a2df23f623 および bazel build //... を使って再現します。まず tests/runtime_env_toolchain:bootstrap_script_test、tests/runtime_env_toolchain:toolchain_runs_test、tests/exec_toolchain_matching:test_exec_matches_target_python_version のログから始めます。これらの Windows チェックがリグレッションなしでパスすれば完了です。
