* refactor(javascript): break the semantic analysis import cycle Split shared semantic facts out of the analysis hub so projectors of effects, evaluation, and identity no longer import one another in a cycle. * 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. --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com>
