N0zoM1z0 00a3078148 fix(build): preserve native generated-file line endings
Treat CRLF and LF as equivalent when checking committed text artifacts so Windows package lifecycles do not report false drift.

When real generated content changes, retain the existing artifact's line-ending convention and cover both check and update behavior with a focused regression test.
