# Build from a clean checkout of the release tag so --version reports the
# tag; a DIST outside the checkout keeps the tree clean. cgo is off: every
# dependency is pure Go. -tags release marks the binary as a release build
# (dun's update.OfFile reads it; no file uses the tag). Upload with
#   gh release upload <tag> $(DIST)/*
