Describe the bug
list.exists(inline_var, inline_var == 1)

Here, inline_var is a shadowed variable which should not be a candidate for inlining.

Expected behavior
inline_var should not be replaced

Additional context
This logic should be ported over: https://github.com/google/cel-java/blob/5039bf9626a91905603d57fdb403c83007548236/optimizer/src/main/java/dev/cel/optimizer/optimizers/InliningOptimizer.java#L136-L153
