Bring the living documentation in line with what the five passes actually
shipped, and correct the claims they superseded rather than leaving them to
mislead: the module UI context is six members, not five; module styling is
compiled CSS, not inline objects only; the strict manifest is version 7.
Also close a silent failure the new contribution mechanism introduces. A
contribution whose target capability nobody provides — or whose provider moved
outside its declared range — is not published, and the manifest is valid and
the artifact exists, so an operator sees a screen that renders nothing with no
error anywhere. `pnpm modules:validate` now lists each declared contribution
with its capability and range and says whether a compatible provider is
installed, and Doctor's discovery check reports the same per module. Both
derive from the publication registry the API serves from, so neither can
disagree with what a running platform would actually publish.
