Our date filter used two qualifiers ("created:>START created:<=END"),
which isn't valid range syntax, so GitHub ignored it and returned every
open issue. Use a single "created:START..END" range. Also fix the window
math, which was a business day too recent and excluded its start day.

GitHub issue search can't express the one filter we want here: "created
at least one business day ago." That's the whole reason the project
board #\87 exists — since we can't save it as a search, we keep a
project's membership in sync to stand in for it.
So: an hourly workflow runs script/github-triage-queue-board.py, which
adds the open issues that fall in the eligibility window to project #\87
and removes the ones that have aged out. Also wires the workflow into
the community automation failure Slack alert, so if it breaks we hear
about it.
