  "message": "Include configuration mnemonic in action execution error messages\n\nWhen an action execution fails, `CommandFailureUtils.describeCommandFailure` previously formatted the error without the configuration mnemonic/checksum:\n\nBefore:\n```\nERROR: /path/to/pkg/BUILD:1:1: CppCompile hello_binary.o failed: (Exit 1): gcc failed: error executing CppCompile command (from target //:hello_binary) /usr/bin/gcc ...\n```\n\nIf `//:hello_binary` failed when built under a configuration transition (e.g. as a dependency of `//:broken_hello_filegroup`), users could not see from the error output why the action failed in that context but succeeded when built directly.\n\nAfter:\n```\nERROR: /path/to/pkg/BUILD:1:1: CppCompile hello_binary.o failed: (Exit 1): gcc failed: error executing CppCompile command (from target //:hello_binary [k8-fastbuild-ST-4e2b1c0a]) /usr/bin/gcc ...\n```\n\nThis CL includes the configuration checksum / mnemonic in action execution error messages, making transition-specific failures immediately identifiable.\n\nFixes part of https://github.com/bazelbuild/bazel/issues/18139.\n\nPiperOrigin-RevId: 970402874\nChange-Id: Iba3dab59f3e0a2229f5e1ccea5db9589727d05c7\n",
