* refactor(javascript): break the semantic analysis import cycle
Split shared semantic facts out of the analysis hub so projectors of

* refactor(javascript): share the import specifier reader
Read static imports in one module used by the boundary checker and both
cycle guards, so those rules cannot drift apart.
