feat(seo): noindex collections and repo hubs, drop their sitemaps

❓ Type of change

• 👌 Enhancement

📚 Description

Owner decision: "we don't need these indexed". Author profiles, collections, owner hubs and multi-Skill repository hubs now render noindex,follow. They stay live and linked. The authors and sources sitemaps are gone from the index and the module config.

A single-Skill repository hub is the Skill's own page. It stays index,follow when the trending admission rule admits it, and the skills sitemap still lists it. The sitemap equals the indexable set, and X-Robots-Tag repeats the meta, as in #322.

A hub that renders a Skill emits no robots tag of its own, so the Skill page decision is the only one on single-Skill hubs.

Loose end: the /gh/<owner> hubs were in sources.xml too, so they go noindex with the rest. Otherwise they would be indexable and unlisted.
