描述

Describe the bug

GraphLearn has implies int64_t as OID_T (see types.h) and current gremlin engine doesn't support string oids as well (see https://github.com/alibaba/GraphScope/issues/1265).

An exceptions should be thrown in g.graphlearn()/g.gremlin() is the oid type of vineyard graph is not compatible with those two engines.

研究方向
Investigate the g.graphlearn() and g.gremlin() functions in the GraphScope codebase to identify where to add the type compatibility check. Refer to the types.h file (graphlearn/core/graph/storage/types.h) which defines OID T as int64 t. The exception should be thrown when the vineyard graph's OID type is not compatible. Also consider checking the linked issue #1265 for context on gremlin engine limitations. The fix should be localized and throw an appropriate error message.
