docs: cce-ui shapes text with cosmic-text directly, not glyphon

glyphon was a wgpu text renderer; with the wgpu path retired, none of its own
API was reachable and every item cce-ui used from it was a cosmic-text
re-export. cce-ui now depends on cosmic-text directly (pinned to the version
glyphon resolved to) and re-exports it for clients, which takes wgpu out of
the DE build entirely. No compositor code change — its own text path is
fontdue, as this file says.
