format command output missing trailing newline

[ajitpratap0]

Description

The format command output does not end with a newline character, causing the shell prompt to appear on the same line as the output.

Reproduction

echo "SELECT * FROM users" | gosqlx format -
# Output: "SELECT * FROM users"% (prompt on same line)

Expected

Output should end with \n so the shell prompt appears on the next line, consistent with standard Unix tool behavior.
