feat(collector): add Go 1.26 runtime metrics support
Add support for 6 new scheduler metrics introduced in Go 1.26: - /sched/goroutines-created:goroutines (counter) - /sched/goroutines/not-in-go:goroutines (gauge) - /sched/goroutines/runnable:goroutines (gauge) - /sched/goroutines/running:goroutines (gauge) - /sched/goroutines/waiting:goroutines (gauge) - /sched/threads/total:threads (gauge) These metrics enable production monitoring for detecting lock contention, syscall blockages, scheduler bottlenecks, and CPU capacity issues. Also includes: - Regenerated Go 1.25 test files for Go 1.25.6 compatibility - Fixed flaky TestTimerObserve test by adding minimum delay - Updated supported_go_versions.json to include Go 1.26rc2 Signed-off-by: Kemal Akkoyun <kakkoyun@gmail.com> Signed-off-by: Kemal Akkoyun <kemal.akkoyun@datadoghq.com>
