fix(es/module): handle Windows backslash paths when detecting relative imports The previous fix checked for Unix-style relative path prefixes (./ and ../) but on Windows, diff_paths returns paths with backslashes. This caused the code to incorrectly add ./ prefix to paths like ..\url-alphabet\index.js, resulting in ./..\url-alphabet\index.js instead of ..\url-alphabet\index.js. Fixes CI failures on Windows.
