Reduce ClickHouse Local Prompt to Smiley Face for macOS

Official CH changelog text
Reduce clickhouse-local prompt to just :). getFQDNOrHostName() takes too long on macOS, and we don't want a hostname in the prompt for clickhouse-local anyway. #65510 (Konstantin Bogdanov).
The prompt for clickhouse-local is simplified to just :) to improve startup speed and avoid unnecessary hostname resolution.

Why it matters

On macOS, the function getFQDNOrHostName() used to determine the prompt takes a long time to execute. Since the hostname is not essential for the clickhouse-local prompt, this change reduces user wait time by replacing the prompt with a simple and fast :) indicator.

How to use it

No user action is required. After updating to the new ClickHouse version, the clickhouse-local prompt will automatically show as :) with improved responsiveness.
