config: populate myst.yml site metadata

Port description, nav, domain, and logo from config.yaml.
Rename static/ → assets/ (Hugo directory convention; MyST does
not serve static/ automatically — assets/ is the expected path).

No dark logo or favicon: neither existed in the Hugo static/ dir;
MyST supplies a default favicon. Footer/quicklinks deferred per ADR 0005.
