fix: add timeouts to dagger query, docker info, and portfile loop (#347)

Three unguarded blocking calls caused CI to hang until the 60-min timeout:
- dagger query prune steps had no timeout; || true only catches errors, not hangs
- docker info (added in d905cd6) had no timeout if Docker socket is unresponsive
- until portfile loop in check-dagger spun forever if otel-receiver.py crashed

Fixes: timeout 120 on all dagger query prune calls, timeout 30 on docker info,
and a kill -0 process-alive guard on the portfile until loop with fallback.
