The coverage pages led with a percentage and an "x of y" count, and every
table listed the modelled operations Spinifex does not implement, which reads
as a scorecard against AWS rather than a statement of what the platform serves.
A published page now opens with the operation count alone, tables the
operations the gateway serves, and carries a separate not-applicable table with
each reason inline instead of footnotes. The unimplemented operations and the
counts move to docs/coverage/internal-report.md, which no docs-site slug points
at. A service with no implemented operations has no publishable page.
* docs: bring doc titles and descriptions into SEO length limits
Rewrite the frontmatter title and description of every published doc so the
rendered <title> lands in 50-60 characters (including the site suffix) and the
meta description lands in 150-160 characters.
* docs: move SEO titles to a seoTitle field and restore display titles
The frontmatter title renders as the page H1 and the sidebar label, so tuning it
for the title tag shortened nothing and lengthened the visible navigation. Put
the search-facing string in seoTitle and give title back its original value.
