Sed escape-sequence handling through the heredoc lost the \1
backreference, yielding an empty VERSION. Switched to
awk -F'"' '/^version/{print $2; exit}' which is simpler and resistant to
quoting. First full end-to-end signed build validated v0.6.1 deployed
and verified against the Microsoft cert chain.
