Move docs/ package mirror into document-navigator plugin

Relocate the ~6k-file docs tree from the repo root into
plugins/document-navigator/docs/ so the plugin is self-contained and
portable. docs/superpowers/ (specs and plans) stays at the repo root.

Moved via cp+rm rather than git mv because directory rename() fails with
EPERM on this WSL /mnt DrvFs mount; git rename-detection pairs the
identical-content files at commit time.

+# @suaveplan/colour-convert-adapt - Bradford chromatic adaptation between XYZ illuminants for ICC-style colour management
+
+Bradford chromatic adaptation for XYZ colour coordinates. Chromatic adaptation adjusts a colour's appearance so that it looks the same under different light sources (illuminants). The Bradford transform is the industry-standard method, used in ICC colour management and many colour science toolkits.
