Render bounds opening the tab and rendering the page with one deadline
(TabOpenTimeout 5 s plus RenderTimeout 20 s), so a hung Chrome no longer
holds the crawl's render lock until the job timeout.
- schema: types per kind, @id links, every node kind, the publisher and
local business, every validator rule, custom JSON-LD caps and merge
- crawl: HTML parse, each check's positive and negative case, fix routes
with the fitting tool, the rendered comparison, allowRequest,
resolverRules and NewRenderer
- pagination, alternates and x-default, primary parents, the filter's
addresses, registry paths and fields, auto-link addresses
