feat: advertise API Platform skillset on help page and footer

Add an 'AI coding agents' band to the /help page and a footer link,
pointing to the skillset (github.com/api-platform/skillset) and the new
docs page (/docs/core/ai-agents). Reuses existing Heading/Button
primitives and the footer link shape — no new bespoke components.
