The R version analysis should assume when resolving versioned (base-R) exports (see solver.sigdb.assumedRVersion):
an explicit pin wins, otherwise a real detected version (from the engine's rVersion(), ignoring none/unknown),
otherwise DefaultAssumedRVersion. Pure and synchronous, so a resolver can call it per lookup.
