- Remove unused filterNewResults import (events batch-add-results legacy
path was removed in Phase 4 Task 4).
- Replace import() type annotation in sync-tournament-results test with
a top-level type import (consistent-type-imports rule).
- Hoist tableName helper out of makeFakeDb closure so it's not recreated
per call (consistent-function-scoping rule).
- eqeqeq: replace `!= null` with explicit null/undefined checks in
tournament-identity.
