Go 1.25 added a new `decoratemappings` setting that controls whether the Go
runtime annotates OS anonymous memory mappings with context about their
purpose. These annotations appear in /proc/self/maps and /proc/self/smaps as
"[anon: Go: ...]". This setting is only used on Linux. For Go 1.25, it defaults
to `decoratemappings=1`, enabling annotations. Using `decoratemappings=0`
reverts to the pre-Go 1.25 behavior. This setting is fixed at program startup
