Refactor NodeCG runtime preparation and update handling

- Updated paths and configurations in doctor.mjs and prepare-nodecg-runtime.mjs to use new build-config.mjs imports.
- Enhanced runtime installation checks and permissions validation.
- Introduced new update configuration management in update-config.ts, including loading and validating update settings.
- Implemented update service for managing update checks and downloads in update-service.ts.
- Replaced update-utils.ts with update-schema.ts for better structure and clarity in update handling.
- Added comprehensive tests for update download and settings management.
- Ensured secure handling of download URLs and improved error handling in update processes.
