Research direction

Investigate the `findVariable` function (likely in the hover provider code) to understand why it returns undefined when a local variable has the same name as a register variable. Check the hover provider implementation and variable scope resolution logic. Look for any existing tests or similar issues. Then implement a fix to handle name collisions between local variables and register variables.
