/**
 * Migration 049: Add default_fast_mode column to the settings table.
 *
 * Adds a new column for the workflow default fast mode setting:
 *  - default_fast_mode (INTEGER DEFAULT 1): whether new features default to fast mode
 *
 * Default is 1 (true) so new and existing installations get fast mode as the default.
 * Guards against duplicate column errors using table_info pragma.
