Introduces a two-LLM-call pipeline: the first call classifies the user's
message intent as "edit", "info", or "help". Edit messages proceed through
the existing routing → edit → propose flow. Info messages get a generated
response about site content from the manifest. Help messages get a
templated capabilities overview. This handles open-ended questions like
"What can I do?" or "What does my site have on it?" which previously
had no path through the system.
