fix(install): simplify to the direct /releases/download/latest/ URL

Gitea serves the most recent release under the `latest` tag segment, so
`/releases/download/latest/nuwiki-ls-<target>.tar.gz` resolves directly
(HTTP 200) — no API lookup or JSON parsing needed. Drop the
latest_asset_url helpers added in the previous fix; the only real bug was
the URL shape (`/releases/latest/download/` is GitHub-only and 404s on
Gitea). Both install paths now just pick the target and build the URL.
