Two confirmed fresh-node failure modes made 'install LND' fail on the
first try and succeed on the second:
- The dependency gate failed fast when Bitcoin was still mid-install
(image pulling, container not created yet): DepProbe.existing only
covered 'podman ps -a', so an in-flight dependency looked identical to
'not installed at all'. The probe now also reports packages in
Installing/Updating state, and the gate waits up to 30 minutes for an
in-flight dependency install to finish (surfacing 'Waiting for X to
finish installing…' on the card) before its normal 3-minute
started-but-not-running window.
- Image pulls had a hard 300s per-URL wall clock, which killed
slow-but-progressing pulls of large images (LND on fresh-node WiFi);
the retry then succeeded off the warm layer cache. Pulls are now
stall-aware: killed only after 3 minutes with no podman output AND no
byte movement in the staging dir, with a 30-minute absolute ceiling.
Dead registries still fail in ~3 minutes.
Adds dep-gate unit tests for the in-flight-install wait and the
neither-installed-nor-installing fail-fast.
