Infer constraint not satisfied in conditional type

Type '.*' does not satisfy the constraint '.*'.*infer

Fixes

1.Add an explicit constraint to the infer clause: infer U extends string
2.Wrap the inferred type in a conditional check before using it
3.Ensure the input type actually extends the pattern you're matching against
