Image detail, search width, and a breakdown of every reply
- Added a per-reply breakdown: long-press a reply for its timings, what the cache reused, and prefill and decode speeds.
- Added an image detail setting for vision models, trading speed against how much of a picture is read.
- Added a setting for how many results a search returns.
- Added a cancel button to downloads, and copying a reply as Markdown.
- Improved web page reading and pasted links.
- Fixed a greeting answered as a date.
