check-and-fix

Run the following commands in parallel to identify and fix errors:

1. Run bun run typecheck to identify TypeScript errors
2. Run bun run lint:fix to identify and automatically fix linting errors

Then fix remaining errors:

1. Fix each TypeScript error found by:
   • Reading the affected files
   • Understanding the error context
   • Making the necessary code changes to resolve the errors
2. If there are any remaining linting errors that couldn't be auto-fixed, manually fix them
3. Run both bun run typecheck and bun run lint:fix again to verify all errors are resolved. IF THE ERRORS ARE NOT RESOLVED, REPEAT THE ENTIRE PROCESS.
4. Run bun run test in the root to ensure no tests were broken.
5. Provide a summary of what was fixed

Be thorough and ensure all errors are resolved and tests pass before completing the task.
