Note

Introduces query ID auto-generation and end-to-end propagation for tracing requests and failures.

• Client adds Builder.setQueryIdGenerator(Supplier<String>) and auto-fills queryId in QuerySettings/InsertSettings when missing; retry/error logs now include queryId
• Exceptions updated: ClickHouseException holds queryId; ServerException now includes queryId, constructor updated, and common ErrorCodes enum added; HTTP helper extracts X-ClickHouse-Query-Id and injects into messages/wrapped exceptions
• JDBC: new DriverProperties.QUERY_ID_GENERATOR; StatementImpl/WriterStatementImpl use generator and expose last query ID; JdbcConfiguration wires supplier from connection properties
• Records now exposes getQueryId(); minor copy edits and Client fields finalized
• Tests added for query ID propagation and server error codes across client and JDBC
