fix: typecheck line_endings.py and create editorconfig stub

Typecheck codemcp/line_endings.py and fix errors. Typecheck ONLY this file (typecheck command takes a filename as argument). As part of this you will need to generate a stub file for editorconfig. Do this by hand, you ONLY have tools accessible to you as described in prompt.
