feat: add database-level default connection configuration support
Implements database-level default storage connection configuration allowing databases to specify default connection settings that tables automatically inherit during creation. Key features: - CREATE DATABASE OPTIONS syntax with DEFAULT_STORAGE_CONNECTION and DEFAULT_STORAGE_PATH - ALTER DATABASE SET OPTIONS for updating connection defaults - Automatic table inheritance of database defaults during CREATE TABLE - Paired validation requiring both connection and path options together - Tables can override database defaults with explicit table-level connection options
