Switch site build from @doc to @doc-full
Use @doc-full instead of @doc so the reference docs include the full
dependency tree (source pages, all library docs). Update:
- build-site.sh: @doc-full and _html_full output path
- gen_rules.ml: (alias ../doc-full) dependency
- site/dune.inc: regenerated
Sidebar: filter ungrouped packages to a whitelist of monorepo
packages under an "Other" group, since @doc-full includes hundreds
of opam dependencies that would clutter the sidebar.
