Add .gitattributes and tighten .gitignore

Normalises text to LF and marks the migrated WordPress uploads (204 PNGs,
94 JPGs, plus GIFs/PDFs/ICO/MP4) as binary so git stops trying to diff,
merge or rewrite endings in them. src/styles/global.css came out of the
theme with CRLF endings and is renormalised here in one deliberate pass
rather than leaving it to surprise someone on a later commit -- the
content is byte-identical ignoring whitespace.

.gitignore additionally covers .vscode/, *.log, *.swp, Thumbs.db and all
.env variants -- the last of those matters because scripts/export-wp.mjs
reads the WordPress DB credentials from the environment.

Also corrects the note on the excluded 80MB video: it lives in public/
and Astro copies it into dist/ on every build, so no manual copy step is
needed, contrary to what the old comment claimed.
