Pull request overview

This PR refactors string formatting across 15 files in the Rspack codebase by converting traditional string literals with escaped newlines (\n) to raw string literals (r#"..."#). This is a pure refactoring that improves code readability by making multi-line string content more visually apparent, without changing any runtime behavior.

Key changes:

• Converted format strings from escaped newline style to raw string literals
• Applied consistently across core runtime templates and multiple plugin modules
• Preserved all existing indentation, whitespace, and formatting in generated output
