This commit refactors the AST substitution logic to correctly handle nested expansions and improve the inlining of lambda expressions. The changes include: - Extracting the core value from potentially expanded AST nodes before checking their kind. - Ensuring that lambda expressions with empty upvalues are correctly substituted. - Adding support for inlining global get expressions as AST substitutions. - Improving the `UsageInfo` collection to correctly track assigned values.
