vitest runs at most four workers instead of one per core; minWorkers is
set to 1 because vitest 2 rejects a maxWorkers below its default
minWorkers. test/cli/bin.test.ts compiles the sources bin/quak.ts imports
and starts libsodium once, before its tests run. The fake accounts in
test/ente-server.ts and test/thumbnails/thumbnails.test.ts use
libsodium's lowest Argon2id cost, since each login runs the KDF again.
