fix: handle ps.tree() failure gracefully in kill() on Alpine Linux

On Alpine Linux (and other environments using BusyBox), the ps output
format differs from standard GNU/procps ps. The @webpod/ingrid parser
used by @webpod/ps cannot parse BusyBox output and throws a TypeError
when kill() attempts to collect child processes via ps.tree().

Wrap the ps.tree() loop in a try/catch so that parse failures fall
through to the direct process.kill() call below. The parent process
is still killed; child processes may survive in degraded environments,
but the caller no longer receives an unexpected TypeError.

Fixes #1369
