feat(assistant): Ask presets in the file state

A row of canned questions matching every staged file's kind, plus Compare
for two or more files: one click asks it, Shift+click puts it in the input
to edit first. Defaults live in Presets.js and the list in use in Prefs, so
a future drawer settings page can edit it; a saved list that does not
validate reads as the defaults. Each prompt asks for an answer in the
document's language. Code and configuration get their own kind, so a
script is offered Explain and Review rather than Summarize. Button's
clicked signal carries the mouse event for the Shift check.
