Fix: robots.txt declares Content-Signal AI-usage preferences

Web-audit fix skill for the content-signals check (Bot & crawl policy, SHOULD).

Goal

Declare Content-Signal AI-usage preferences in robots.txt.

Fix

Add Content-Signal directives to robots.txt (contentsignals.org): ai-train, search, and ai-input set to yes or no. They express usage preferences at a finer grain than a blanket allow/deny.
