Snowflake supports structured ARRAY types such as
ARRAY(VARCHAR), while the parser currently treatsARRAYas untyped and leaves the parenthesized type unconsumed.This adds a dialect capability for
ARRAY(element_type), enables it for Snowflake and ClickHouse, and parses it intoArrayElemTypeDef::Parenthesis. Existing ClickHouse behavior is preserved.Validated against:
https://docs.snowflake.com/en/sql-reference/data-types-structured#label-structured-types-array
Tests cover CREATE TABLE and CAST round trips.
