chore(git): check out every text file with LF, not only Go and scripts

.gitattributes forced LF only for Go, shell, generated files, snapshots
and deploy YAML, so a Windows clone with core.autocrlf=true got CRLF
everywhere else. On that working copy `make format-check` flags 198
frontend files, `msw-worker-check` sees mockServiceWorker.js differ from
the installed copy, and TestAnalystContextNamesRealCIJobs and
TestReviewNamesRealCIJobsAndGates find no ci.yml job at all, while Linux
CI stays green. `* text=auto eol=lf` extends 5c5a5096 to every text
file. No committed blob changes: the index already holds LF everywhere,
and binary detection still leaves the 50 binary files alone.

An existing Windows clone applies it with a fresh checkout on a clean
tree: `git rm -rq --cached . && git reset -q --hard HEAD`.
