Protobuf/Buf Formatter Fails for Files Larger than 64KiB

使用一个大于 64 KiB 的有效 .proto 文件重现该故障，并运行 spotlessApply。首先阅读 ProcessRunner.start 以及跟踪信息中显示的调用点 BufStep.java:109；当格式化完成且没有 Broken pipe lint、生成的输出仍然有效时，即表示完成。

Test case:

1. Define a .proto files larger than 64 KiB (or your platform's pipe buffer limit). Padding with whitespace should also work.
2. Configure spotless to format said file.
3. Run spotlessApply (gradle example).

Expected behavior:

Formatting runs and passes (if valid proto file).

Actual behavior:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':treatment:api:spotlessProtobufApply'.
   ...
Caused by: org.gradle.api.GradleException: There were 1 lint error(s), they must be fixed or suppressed.
src/...:LINE_UNDEFINED buf(java.io.IOException) Broken pipe (...)
Resolve these lints or suppress with `suppressLintsFor`
