Description

With "Show Variable Types -> At Top of Function" enabled, we show a lot of variables that are never used across the ILs.

We shouldn't.

Similarly, we should also clean up the function.vars list, but that might need to be a seperate/higher-effort ticket.

Research direction

Start by tracing the "Show Variable Types -> At Top of Function" behavior and how variables are collected across the ILs. Verify which variables are unused, then confirm that unused variables no longer appear in the displayed list. Cleaning up the separate function.vars list is identified as a higher-effort follow-up rather than required scope.
