- Updated exports in `index.ts` to include `unitSet.js`.
- Introduced new types for crew types and their requirements in `types.ts`.
- Implemented `unitSetLoader.ts` for loading unit set definitions from JSON files.
- Created `che_징병.ts` action for recruiting crew types with cost and training calculations.

- Added tests for crew type availability and unit set parsing in `crewType.test.ts`.
