Replace the manual malloc/realloc/free memory management in jsonpull with std::shared_ptr ownership. Each json_object now owns its children through std::vector<json_object_ptr>; raw back-pointers to parent and parser remain valid by structural invariant and are cleared on json_disconnect so detached subtrees can outlive their parser. Strings become std::string, child arrays become std::vector, and the old union becomes a struct so non-trivial members can coexist while preserving the existing o->value.xxx access paths. The old jsonpull.c is replaced by jsonpull.cpp, json_stringify now returns std::string, and all callers across tippecanoe, tile-join, tippecanoe-decode, tippecanoe-json-tool, tippecanoe-overzoom and the unit tests are updated to use json_object_ptr / json_pull_ptr.
