notes.trustroots.org redirects

This GitHub Pages site keeps legacy notes.trustroots.org links working while Nostroots web content lives at nos.trustroots.org.

• / redirects to https://nos.trustroots.org/
• /more.html and /more/ redirect to https://nos.trustroots.org/background/
• unknown paths use 404.html as a best-effort path-preserving redirect to https://nos.trustroots.org
