Where the writing gets checked

Every team, grouped by the sector it works in, with what its repos do counted rather than claimed.

The first commit of each team's .vale.ini, or of the first CI file that names Vale, in the repo checked; a style package counts from the day its repo was created. 14 teams without a public repo are not dated.
