Replaced singleFork:true + sequence config with the simpler fileParallelism:false
which correctly serializes test file execution. The previous singleFork approach
ran tests from multiple files concurrently within one process, allowing the global
afterEach cleanup (test/setup.ts: truncates lists/listShares) to delete rows mid-test
in another file, causing intermittent FK violations (ER_DUP_ENTRY, ER_NO_REFERENCED_ROW).
fileParallelism:false runs one test file at a time so afterEach cleanup for file A
never races with insertions from file B.
