name: Build (Linux + macOS)

# Compile checks on the platforms users build from source on. These are BUILD
# CHECKS, not releases: the README deliberately ships no prebuilt Linux binary,
# and an unsigned macOS build is not something to hand a stranger. The point is
# to catch a break in the PR that causes it rather than in a user's bug report.
#
# The Windows portable zip -- the one artifact users actually download -- is
# built by windows-portable.yml.
