Reframe seed-article banners as community contribution invitations

The 35 articles still in their seed form previously carried a banner
reading "Seed article. ... Domain stewards should expand, restructure,
and refine as needed." For a community preview, that phrasing reads as
"TODO left in production" to first-time visitors.

Replace all three banner variants (performance-seeded, security-seeded,
community-ported) with a single positive invitation:

> Contributions welcome — open a PR to refine or extend this article.

Content and structure of the articles are unchanged; only the leading
quote block differs. Articles that had their banner fully stripped in
the earlier triage pass (the showcase-grade ten) are unaffected.
