Summary

Fixes #300 - Support for DEFAULT (now()) and other function calls wrapped in parentheses in CREATE TABLE statements.

Problem

The MySQL 8.0 syntax DEFAULT (function()) was failing because the translator only consumed a single token after the DEFAULT keyword. For expressions like DEFAULT (now()), it would only capture the opening parenthesis (, causing the query translation to fail.

Solution

Enhanced the DEFAULT clause handler in WP_SQLite_Translator to:

• Detect when a DEFAULT value starts with an opening parenthesis
• Track parenthesis depth to consume the complete expression
• Handle nested parentheses correctly
