fix: resolve TypeScript errors after nodeDebugFlags removal

Fixed type errors introduced by removing nodeDebugFlags:
- Removed getNodeDebugFlags import from constants.mts (3 occurrences)
- Added SpawnResult type import to dlx/spawn.mts
- Fixed PromiseSpawnResult to Promise<SpawnResult> type conversions
  using double cast via unknown as TypeScript requires
