   I’ll work on the JDBC mapping for this. The current driver inherits an empty 
`getTypeInfo()` result even though `FlightSqlClient` already exposes 
GetXdbcTypeInfo.
   
   I’ll keep the change in the JDBC metadata bridge and test it against an 
in-process Flight SQL server: the 18 JDBC columns, CREATE_PARAMS conversion, 
nullable values, empty results, server failures and stream cleanup. Existing 
protocol fields and server ordering will be preserved.
