fix(build): resolve TypeScript error and lint output issues

- Exclude vitest.config.ts from main tsconfig to fix import.meta error
  (vitest.config.ts uses ESM syntax incompatible with CommonJS module setting)
- Replace logger.error('') with console.log('') in lint script to prevent
  spurious red ✗ symbol when adding newlines
