Added three agent-discovery signals — sitemap, AGENTS.md, and a robots.txt Content-Signal directive — and rebalanced the scored set to keep it at 100.

- addedAGENTS.md — checks for an emerging plain-Markdown agent guide. Shipped as a bonus signal (shown, not scored) — adoption is still early.
- addedContent-Signal — checks whether robots.txt declares content-usage preferences (search / AI answers / AI training). Bonus signal, reflecting Cloudflare's emerging Content Signals convention.
- changedRebalanced the scored set to keep it at 100 while adding the sitemap check: structured data 6→4 and llms.txt 3→2 (both low-lever hygiene). No site's underlying readiness changed — only the standard.
