Reconnect K8s log stream on silent API disconnects

The adapter opened a single follow-stream to the K8s API for pod logs.
If that TCP connection silently dropped (API server hiccup, network
timeout, load-balancer idle cut), streamPodLogs returned early and no
more real Claude output reached the UI — only keepalive pings.  The
pod kept running and producing logs (visible via kubectl), but the
adapter never reconnected.

Splits streamPodLogs into streamPodLogsOnce (single follow attempt) and
a reconnecting wrapper that retries with sinceSeconds until a shared
stop signal fires when waitForJobCompletion resolves.  On reconnect,
requests logs from the original stream start time (+5s overlap) so no
output is lost; the UI deduplicates chunks.

Bumps version to 0.1.12.
