Subject: [PATCH] feat(agent-readiness): declare Content-Signal in robots.txt
 (#3327)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Per contentsignals.org draft RFC: declare AI content-usage
preferences at the origin level. Closes #3307, part of epic #3306.

Values:
  ai-train=no   — no consent for model-training corpora
  search=yes    — allow search indexing for referral traffic
  ai-input=yes  — allow live agent retrieval (Perplexity,
                  ChatGPT browsing, Claude, etc.)
