fix: Remove unused reset parameter from stats___mcp_query_rules()

Change function signature from stats___mcp_query_rules(bool reset) to
stats___mcp_query_rules() to match MySQL query rules pattern.

The reset parameter was never used in the function body and MySQL's
stats___mysql_query_rules() has no reset parameter.
