Play Framework

fix(bundle): match PF-120 graceful-drain window in bundle-play.sh, drop kill -9 (PF-128)

bundle-play.sh's stop branch waited only 10s then issued an unconditional
kill -9, hard-killing a clean-but-slow shutdown mid job-drain and truncating
in-flight work — exactly what PF-120 fixed on the Gradle path. Raise the
graceful window to ~35s (past play.jobs.stopTimeout's 30s default) and drop
the SIGKILL, mirroring PlayStopTask: send SIGTERM, then leave reaping to the
OS. Preserve the pid file on the still-draining timeout path so status/pid
keep tracking the live process. Cross-reference comment added to keep the two
copies of the lifecycle logic in sync.
