fix(install): fetch latest OpenBoot binary from GitHub releases instead of Homebrew tap

Homebrew caches tap formula versions and only updates when the user runs
`brew update`, so users were getting stale versions (e.g. v0.55.2) even
when newer releases were available. The generated install script now
queries the GitHub releases API at runtime to get the true latest version
tag and downloads the binary directly, bypassing the tap entirely.
