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.

 ### Commits
 
 1. `config: populate myst.yml site metadata`
-   - Files: `myst.yml`
-   - Add `site.title`, `site.domain`, `site.description`,
-     `site.options.logo`, `site.options.logo_dark`, `site.options.favicon`,
-     and `nav:` from `config.yaml`'s `params.navbar`.
+   - Files: `myst.yml`, `assets/images/logo.svg` (renamed from `static/images/logo.svg`)
+   - Add `project.description`, `site.options.domain`, `site.nav`,
+     and `site.options.logo` from `config.yaml`'s `params`.
+   - `site.options.logo_dark` omitted — no dark logo exists in the repo.
+   - `site.options.favicon` omitted — MyST provides a default favicon;
+     no `favicon.ico` was present in the Hugo `static/` directory either.
+   - Rename `static/` → `assets/` (Hugo directory convention → MyST
+     convention; MyST does not serve `static/` automatically).
    - Why: feature parity for everything except footer/quicklinks, which
      ADR 0005 defers.
