Go 1.25 corrected the semantics of contention reports for runtime-internal locks,
and so removed the [`runtimecontentionstacks` setting](/pkg/runtime#hdr-Environment_Variables).

Go 1.25 (starting with Go 1.25 RC 2) disabled build information stamping when
multiple VCS are detected due to concerns around VCS injection attacks. This
behavior and setting was backported to Go 1.24.5 and Go 1.23.11. This behavior

## Changes since v1.2.4
