Walkthrough

The changes add explicit TypeScript typings and improve code quality in the simulator modules file. The getNextPosition function now includes parameter type annotations with defaults and an explicit return type. The global modules registry is converted from a mutable variable to a typed constant using Record<string, any>. The done variable is similarly typed as Record<number, number>. The changeInputSize function gains explicit parameter and return types along with documentation. Size normalization is updated to use string conversion before integer parsing, and variable declarations are updated to use const instead of var.
