- Set entry file in nest-cli.json and disabled output directory deletion.
- Updated tsconfig.build.json to extend from tsconfig.base.json and refined compiler options.
- Modified tsconfig.json to extend from tsconfig.base.json and removed unnecessary overrides.
- Adjusted manage.sh script to build BFF using TypeScript compiler directly.
