Description

When using the V2 fallback service protocol (enabled by new_module_registry), the type field in the JSON request body is always "import", even when the module was loaded via require().

Expected Behavior

The type field should reflect how the module was requested:

• "import" - Static or dynamic ES module import
• "require" - CommonJS-style require() call
• "internal" - Import originated from inside the runtime

Actual Behavior

The type field is always "import", regardless of how the module was loaded.

Root Cause

In src/workerd/server/workerd-api.c++, the V2 fallback callback hardcodes ImportType::IMPORT:
