What changed:
- Added an auth package Vitest config with the existing forks pool and a 15s test timeout.
- Kept production bcryptjs salt rounds and test assertions unchanged.
Why:
- On this machine one 12-round bcryptjs hash can exceed Vitest's default 5s timeout, making the auth suite fail even though the implementation succeeds.
Verification:
- pnpm --filter @bytelyst/auth build
- pnpm --filter @bytelyst/auth test
- pnpm --filter @bytelyst/auth exec eslint . --ext .ts,.tsx
