Fix max-processes option bug in TranslateStringsParallel command

- Fixed bug where --max-processes option was not working correctly
- Changed from null coalescing operator (??) to ternary operator (?:)
- Added comprehensive tests for the parallel command including:
  - Testing default value of 5 processes
  - Testing command signature includes max-processes option
  - Testing that multiple processes actually run in parallel
  - Testing process limit is respected
- Default max processes is now 5 instead of 100
- Bump version to 1.7.18
