0.1.31: harden streamPodLogsOnce with Promise.race bail (FAR-10)

Defensive follow-up to the FAR-10 fix.  The original patch aborts the
in-flight follow stream by destroying the Writable once stopSignal
fires, and relies on the @kubernetes/client-node library propagating
that destroy into an abort of the underlying HTTP request.  If that
propagation ever fails (e.g. the client is awaiting a response that
never arrives), logApi.log() can still hang forever.

Adds a Promise.race with a 3s bail timer that starts when stopSignal
fires.  In the happy path (destroy-propagation works), logApi.log()
resolves first and the bail timer is cleared.  In the failure path,
the bail timer fires and streamPodLogsOnce returns with whatever
chunks were captured — preventing the hang from reaching execute().

No test change: existing 267 tests pass and the race path needs a k8s
mock to exercise end-to-end; validated by monitoring real runs.
