Tester had already written a complete, correct test (4/4 steps pass
against a real backend) but stalled investigating DB/migration setup
after its own verification run silently exited with no result -- the
task spec's suggested invocation included --quit, which kills a --script
SceneTree test before its awaited HTTP calls finish (same Godot
--script-mode gotcha documented elsewhere this session).
Renamed smoke_test.gd -> smoke_test_e2e.gd: the task spec named it
without the checkpoint runner's expected smoke_test_*.gd suffix, so
scripts/run_checkpoint_tests.py's glob would have silently never picked
it up. Also fixed the --quit flag in the file's own usage comments.
