add wireframes from current implementation; supersede claude-design

Five wireframes generated via the frame0-wireframe skill, sourced
from JSON and rendered to PNG. Cover the welcome screen and four
main-view states: default, editor-above-Claude (D-49), focus mode
(D-52), sidebar-collapsed (D-51), and ticket detail in the context
panel.

The hi-fi mockups under docs/claude-design/ are now reference-only;
README marks the bundle as superseded and points at docs/wireframes/
as the canonical source. The token files there still feed the
runtime themes per D-43 / D-44, so the bundle is kept rather than
removed.
