www + whitepaper: adopt custom λ mark from MPS, green, 3× wordmark size

Fetched the lumbda-logos artwork from
media.unturf.com/c/fbd3d473-.../lumbda-logos (a MakePostSell product),
applied both flips (vertical + horizontal, = 180°) at bake time so the
PNG ships oriented correctly without any CSS transform dance, and
recolored non-background pixels to brand green (#227842) with alpha
derived from pixel brightness so anti-aliased edges stay smooth.

Two PNG variants ship under whitepaper/diagrams/:
  * lumbda-logo.png        dark ink for print contexts
  * lumbda-logo-green.png  #227842 for web

www/ carries symlinks to both.

Homepage (www/index.html): replaces the CSS-rendered λ with an
<img class="lambda-mark"> element sized 9.6rem — 3× the 3.2rem
wordmark font — stacked below "lumbda." on its own line.

Whitepaper (whitepaper/lumbda-whitepaper.rst): adds the logo as the
first figure above the permacomputer-logo, 24% width, centered.
Regenerated PDF + HTML; embed-images.py base64-inlines the new file
automatically so the HTML stays single-file.

CI (.gitlab-ci.yml): generalizes the symlink resolver from two
explicit `cp -L` calls into a `find www -type l` loop, so every
current and future symlinked asset deploys without per-file CI edits.
