Root cause: bin/garc uses set -euo pipefail. Any command substitution
$(...) that returns exit 1 caused the entire garc process to exit
immediately with no output, making errors look silent.
Fixes:
- ingress.sh: add || true to all _find_queue_file $() assignments
so set -e does not silently kill the process on missing queue items
- ingress.sh: _ingress_update_status returns 1 silently (callers
print their own error); _ingress_done/fail print "Queue item not
found" exactly once
- ingress.sh: _ingress_next result also guarded with || true
- drive.sh: garc drive info with no args now shows GARC workspace
folder info instead of printing usage and exiting
- garc-core.py: replaced 210-line duplicate with a 3-line re-export
from garc_core.py to prevent future divergence
Verified: verify/done/fail all print clear error on bad ID (exit 1),
drive info no-arg shows workspace folder, no regressions.
