Subject: [PATCH] fix(install): detect un-accepted Xcode license before build

Add an xcrun check after verifying Xcode CLT is installed. When the
Xcode/CLT license has not been accepted, cc exits with code 69 and
the build fails with a cryptic linker error. This surfaces a clear
message telling the user to run `sudo xcodebuild -license accept`.
