Enforce that line endings are always stored as LF in git tree (verybadcat#250)

* Initial plan

* Add .gitattributes to fix cross-platform formatting

Normalizes line endings to LF in repository while allowing platform-native
checkouts (CRLF on Windows, LF on Linux). Verified that dotnet format passes
on both platforms without requiring end_of_line in .editorconfig.

* Enforce automatic CRLF to LF conversion

* Update workflows while we're at it

* Fix Release workflow
