Suppress Output of Cancelled Queries in ClickHouse Client

Why it matters

In previous versions, query results could still appear in the terminal even after a user cancelled the query using Ctrl+C. This feature addresses that issue by ensuring no output is shown when a query is cancelled, improving user experience and interaction clarity.

How to use it

Users simply need to cancel their running queries in clickhouse-client using Ctrl+C as usual. The client will automatically suppress any output from the cancelled query without additional configuration.
