Editor

Changed

• Light mode is now the default theme for new and reset editor settings.

• Improved Drizzle dependency ordering, reserved identifiers, safe defaults, minimal imports, and cyclic relation warnings.

Fixed

• Prevented unsafe Drizzle forward and self references from producing brittle generated code.
• Prevented long exporter warnings from overflowing the export modal.
