CI never fails: test step ends with || true #15

Problem

.github/workflows/ci.yml:35 runs the test step as:

npm run test:coverage -- --maxWorkers=1 --passWithNoTests || true

|| true means no test failure can fail CI. Run 32669557867 on main is marked success while its log reports:

FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory
FAIL tests/unit/TraversalQuery.test.ts
FAIL tests/integration/graph-operations.test.ts
Test Suites: 2 failed, 10 passed, 12 total
Time:        946.502 s

Fix

Remove || true. Expect CI to go red until the traversal termination bug is fixed (filed separately).
