Use Claude Haiku 5.5 as Chief's fast model, with a 1M context window
Every member now gets Claude Haiku 5.5 behind Chief's Fast option, so fast answers can draw on far longer conversations and documents, and the Anthropic option in the prompt bar's provider choices names it; a pin on Haiku 4.5 returns to Chief's automatic choice.
Chief's fast option used to run out of room on long conversations and large documents, so a big prompt needed a slower, deeper mode to fit.
Today, we're upgrading Chief's fast option to Claude Haiku 5.5, along with new wording on the Anthropic option in the prompt bar.
