[`tlssecpmlkem` setting](/pkg/crypto/tls/#Config.CurvePreferences).

Go 1.26 added a new `tracebacklabels` setting that controls the inclusion of
goroutine labels set through the the `runtime/pprof` package. Setting `tracebacklabels=1`
includes these key/value pairs in the goroutine status header of runtime
tracebacks and debug=2 runtime/pprof stack dumps. This format may change in the future.
