fix CI and show the logo construction in the developer docs

Clinnet's runtime test sources add the documentation theme that the
portal edge style imports, so the gamma style assertions compile in the
sandbox. The developer-note digests for the changed Nix ranges are
refreshed with no-impact attestations.

The GammaLoop marks now render from the Kurvst knot logo, which exposes
logo and construction functions, so the docs SVG check regenerates the
committed logo. The developer landing page shows the construction
(letter outlines, cut strips and centerlines) in light and dark themes,
and the regenerated portal and about SVGs follow the Kurvst and Linnest
pattern changes.
