feat(release): drop darwin_amd64 (Intel Macs) (#15)

Intel Macs are no longer receiving macOS updates. Drop from release
matrix and re-add to goreleaser ignore list. install.sh now prints
a clear message pointing Intel users to build-from-source. README
manual-install section no longer advertises a darwin_amd64 URL.
