Move the Andrew briefing page to /odooityourself.html

git mv for-andrew/index.html odooityourself.html (history kept) and drop the
now-empty for-andrew/ directory, so the page serves at the flat root URL
https://odoo4projects.com/odooityourself.html with no directory redirect.

Update every reference to the old path: canonical, og:url and the WebPage
JSON-LD url in the page; the sitemap.xml <loc> (replaced, lastmod 2026-10-25,
still 24 entries); and the llms.txt key-page line. Copy, CSS, assets and all
other pages are untouched.

/for-andrew/ was never announced or indexed, so it is deliberately left as a
404 — no redirect added.
