Add release process via goreleaser, restructure Make targets

make targets each do one thing now: lint, fmt, fmt-check, test. Use
'make check' for combined lint + fmt-check + test (the standard
pre-commit gate).

Release builds are pure-Go (CGO_ENABLED=0) cross-compiling to
linux/darwin × amd64/arm64.
