www: canonical slug /lumbda-whitepaper.pdf + embed uncloseai.js

Rename www/whitepaper.pdf → www/lumbda-whitepaper.pdf (symlink target
unchanged; slug now descriptive for search/citation). Update the CTA
and footer links in index.html, plus the .gitlab-ci.yml symlink-resolve
step. Companion Caddyfile redirect in proxy.unturf.com keeps old
/whitepaper.pdf links working via 301.

Add <script src="https://uncloseai.com/uncloseai.js" type="module"> to
<head>, matching www.unturf.com + timehexon.com pattern — brings the
permacomputer chat/AI integration to lumbda.com's front door.
