shopt -s nullglob (set so outer for-loop tolerates empty *.bin) made
an unmatched .inflight-* glob expand to nothing. Bare "ls >/dev/null"
then succeeded by listing CWD, and our if-branch incorrectly skipped
every orphan whose .inflight-* did not match. Net effect: medium-sized
orphan bins (100 MiB+, valid QECCOPS1 magic, no markers) accumulated
in our queue indefinitely across pool restarts.
Replace with compgen -G which returns success only when our pattern
matches, immune to nullglob.
Adds tests/integration/test-heal-orphan-bins.sh as TCRAUDT reducer
covering our contract: medium-size orphan promotes to .ready,
sub-threshold truncated to .done, bad-magic DLQs to dlq/.
Incident 2026-06-14: 8 vecC-tri-*-w8c.bin orphans (493 MiB each, Jun 12
emit) survived multiple foxhop pool restarts. Live factory queue
visible to operator as a persistent ~8-bin floor that never drained.
