Switch from dotted names (e.g. "constants.si") to C++-style :: separator (e.g. "constants::si") for nested namespace declarations, both in the C++ API (register_namespace) and in script (namespace()). The original implementation used . because namespace members are accessed via dot notation at runtime (constants.si.mu_B), making the declaration separator match the access syntax. However, :: is more consistent with C++ namespace conventions and aligns with ChaiScript's existing use of :: for method (def Class::method) and attribute (attr Class::attr) declarations. Member access in scripts remains dot-based (constants.si.mu_B) since that is ChaiScript's member access operator. Requested by @lefticus in PR #675 review.
