Add URL visit detection that triggers a direct page fetch when the
user asks to enter, open, analyze, or read a site along with a URL.
Extend URL extraction to match bare domains (e.g. example.com.br),
deduplicate results, and normalize missing protocol prefixes. Update
the system prompt to instruct the model to treat visited webpage
content as the primary source when [WEBSITE CONTENT FROM ...] tags
are present.
Also rotate conversation context logs for 2026-10-27.
