feat: add VECTOR_FP64 (double-precision) vector support#33
Merged
Conversation
Add FP64 vector type support for schema, documents, and queries: - FFI layer: add schema/docer/getter/query functions for double-precision vectors - Fix has_vector/vector_names/field_names to handle std::vector<double> - Schema: ZVecSchema::addVectorFp64() - Doc: setVectorFp64() / getVectorFp64() - Query: queryFp64(), ZVecVectorQuery::setFp64() flag, queryById() FP64 support - Test: test_fp64_vectors.phpt covering insert, fetch, query, index types Closes #31
- ZVecSchema: addVectorFp64() method - ZVecDoc: setVectorFp64() / getVectorFp64() methods - ZVec: queryFp64() method - ZVecVectorQuery: useFp64 property + setFp64() method - ZVec::query(): route to FP64 path when ZVecVectorQuery.useFp64 is true
