refactor(scripts): extract mirrorRegistryTargets from prepareProjectDir

Browse Source 
Inlining the registry-target mirroring pushed prepareProjectDir to cyclomatic
24, the one complexity finding fallow attributes to this branch — the other
eight are inherited and out of scope here.

Same behaviour, expressed as a filter chain in its own named function, so
prepareProjectDir returns to what it was and the new helper stays flat.
