docs: add initial modules documentation and update error/variable terminology

Create new modules.markdown guide explaining Wren's module system, import syntax, and top-level scoping. Update error-handling.markdown to use "Top-level variable" instead of "Global variable" in error messages. Revise variables.markdown to clarify top-level variable visibility and link to the new modules page. Add "Modules" link to the site navigation template.
