What's changed and what's your intention?

please see the sqlness test json-structured.result first

for compatibility consideration, the table created with datatype JSON is treated as the old json type

Pull Request Overview

This PR adds support for structured JSON format in the database by introducing a new format = "structured" option for JSON columns. The key changes include:

• Added structured JSON format support that uses native struct types instead of JSONB binary format
• Modified JSON datatype parsing to distinguish between structured (native) and unstructured (JSONB) formats
• Updated value-to-gRPC conversion functions to properly handle struct field metadata and return Result types for better error handling
• Updated the greptime-proto dependency to a newer revision that includes struct field support in protobuf definitions
