Subject: [PATCH] chore: pin line endings and editor defaults
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds `.gitattributes` and `.editorconfig`, which the repository has been
without.

`* text=auto eol=lf` makes the checkout independent of each contributor's
`core.autocrlf`. Until now a Windows checkout produced a CRLF working tree
while the repository stored LF, so the two disagreed and any tool that
compares line endings reported differences that were not really there.
Binary types are marked so git never rewrites them.

`.editorconfig` states the conventions the sources already follow — UTF-8,
LF, two-space indent, a final newline, no trailing whitespace — so an editor
applies them without per-contributor configuration.

No file contents change: everything committed was already LF, so
`git add --renormalize` produces no diff.
