Four files were stored with CRLF in git while .gitattributes mandates
`* text=auto eol=lf`, so git reported them as perpetually "modified":
- ROADMAP.md
- backend/app/__init__.py
- backend/app/models/__init__.py
- frontend/src/App.jsx
One-time `git add --renormalize` rewriting the stored blobs to LF. Pure
line-ending change — `git diff --ignore-cr-at-eol` is empty, i.e. zero
content was altered. Windows scripts (*.ps1/*.bat/*.cmd) are untouched;
.gitattributes pins them to CRLF and they were correctly skipped.
