fix(scripts): improve type check error output in check script

When TypeScript type checking fails:
- Always show stdout/stderr (even in quiet mode) so actual errors are visible
- Add clear "Type check failed" message after errors
- Add spacing for better readability

Before: "Check runner failed: command failed" with no context
After: Shows actual TypeScript errors followed by "Type check failed"
