DX-120970 Fix macOS build: pin cmake/boost before brew bundle

Move cmake and boost local-tap setup before the first `brew bundle`
call. Newer Homebrew on macos-15-intel treats `cmake` as a cask during
`brew bundle`, causing the build to fail. Pre-installing from the pinned
local formula ensures brew bundle skips it cleanly.
