Add a cpp-vt-stream example that verifies libghostty headers compile cleanly in C++ mode. The example is a simplified C++ port of c-vt-stream. The headers used the C idiom `typedef struct Foo* Foo` for opaque handles, which is invalid in C++ because struct tags and typedefs share the same namespace. Fix all 12 opaque handle typedefs across the headers to use a distinct struct tag with an Impl suffix, e.g. `typedef struct GhosttyTerminalImpl* GhosttyTerminal`. This is a source-compatible change for existing C consumers since the struct tags were never referenced directly.
