name: Build Windows installer

# The agent's source lives in a private repository whose Actions are currently billing-blocked.
# This repository is public, so its runner minutes are free — it checks the source out with a
# read-only deploy key and attaches the resulting installer to a release here.
#
# The installer is UNSIGNED: no Windows code-signing certificate exists yet. Once one does, the
# private repo's `release-agent.yml` is the proper home for this and this workflow should go.
#
# Note that this repository is public and so are these logs. Keep build output out of them if a
# step would ever echo source.
