Rename the capnproto-dlang fork to zap-dlang: source/capnproto/ -> source/zap/ (module/import paths capnproto.* -> zap.*), compiler plugin capnpc-dlang -> zapc-dlang, schemas .capnp -> .zap, Makefile pkg-config/-lcapnp -> zap/-lzap, README/CONTRIBUTORS rebranded with canonical zap-proto.io/zap-proto.dev/ github.com/zap-proto/d links. Pure mechanical rename: no logic changes. Upstream Sandstorm MIT headers preserved.
