…shared libraries `bn::base::DynamicLibrary` opens a shared library at runtime and unloads it when the object is destroyed. The platform handle can be handed off with `Release()` when the library should remain loaded indefinitely. `Open()` returns either the library or the platform's description of why it could not be loaded. `SymbolScope` chooses whether `GetSymbol()` also resolves symbols from the libraries that the loaded library links against. Each platform restricts this differently, so macOS passes `RTLD_FIRST` to `dlopen()`, other Unixes check which image defines each symbol, and Windows only ever searches the module itself.
