Fix two lint errors introduced by biome 2.4.10 → 2.4.11 upgrade

biome 2.4.11 (bumped via Dependabot in 5eaae30) promoted two rules
in its recommended ruleset:

1. lint/suspicious/noConfusingVoidType (warning → error):
   `Promise<void[]>` is now an error in generic position. Fixed by
   returning `undefined` explicitly from the async lambda so
   `Promise.all` resolves to `Promise<undefined[]>`.

2. assist/source/organizeImports (implicit):
   Import order in definitionServiceTest.ts was out of alphabetical
   order after adding memoryQueueConfig and recomputeHandler imports
   during the recompute refactor. Fixed by running `biome check --write`.
