Pin LF line endings and renormalize the working tree

scripts/validate-char-count.js measures characters on disk, so a CRLF
checkout added ~1 char per line and pushed the 11k-budget prompt files over
the limit depending on how the repo was cloned. Pins eol=lf, marks binaries,
and renormalizes the files that had CRLF.
