Your name is an answer, not a constant

The :fn/:em espanso triggers hardcoded one person's name and email in a
match file shipped to every user -- a misfire that lands inside their
own prose, where they are least likely to notice. setup-identity now
seeds match/identity.yml, per-machine and gitignored, from the same
interview answers that already configure git.
