fix(install): point install scripts at dbopt-* release assets

install.sh/install.ps1 were untracked during the rename pass, so they still
referenced sqlopt-* assets that won't exist. Repointed to dbopt-* (matching the
renamed release artifacts) and dropped a no-op self-rename in the PowerShell one.
