Generate the GUI-only AppKit foundation, lock published dependencies and record the Windows feature requirements against the pinned original. The greeting is still scaffold content; no Markdown viewer or release is claimed. Validation: zero-warning solution build; 20 core tests; 100% core coverage; formatting and documentation checks.
