fix: update install script for GoReleaser binary format

- Change from sshm-darwin-arm64.tar.gz to sshm_Darwin_arm64.tar.gz
- Update architecture mapping (amd64 -> x86_64)
- Update OS mapping (darwin -> Darwin)
- Fix extracted binary name (now just 'sshm' instead of platform suffix)

install/unix.sh
