Research surface now classifies queries across 16 typed intents

The research and chat surface used to dispatch queries with a regex template: fast and cheap, but it failed quietly on anything that didn't match a hard-coded shape. Asking for "compare AAPL and MSFT capital allocation over the last decade" might route to a generic news search instead of the structured comparison view.

The classifier now runs on Anthropic Haiku and returns a typed intent ("compare", "screen", "explain", "macro_lookup", and thirteen others) along with structured entities and a confidence score. The 16 dispatch handlers each render their own component: a stock comparison page looks different from a screener result, which looks different from a macro chart. When confidence is low, the response says so and asks you to clarify, instead of guessing.

If you've been doing research that needed manual workarounds (phrasing things in specific ways to get the right view), try the natural phrasing now. It should mostly just work.
