test: add tests for virtual node filtering in API export

Add E2E and unit tests verifying that virtual nodes (Note, MarkdownNote, Reroute, PrimitiveNode) are excluded from API format export while preserved in standard workflow format. Unit tests confirm graphToPrompt correctly filters isVirtualNode from the output object. E2E tests verify the same through the browser via getExportedWorkflow({ api: true }). Includes a new test fixture (note_with_ksampler.json) combining real and virtual nodes for mixed-workflow assertions.

 ## Status

+Proposed

 ## Context

@@ -42,8 +42,4 @@ Primitives act as a synchronization mechanism — no own state, just a projectio

 ## Decision

-Option A. Override `serialize()` on PrimitiveNode to preserve `widgets_values` through copy-paste. This is the lowest-risk fix with no change to connection lifecycle semantics.
-
-Prerequisite: PR [#10010](https://github.com/Comfy-Org/ComfyUI_frontend/pull/10010) replaced `clone().serialize()` with direct serialization in `_serializeItems`, eliminating the code path that dropped `widgets_values` for widget-less clones. Option A provides the PrimitiveNode-specific fallback for any remaining edge cases.
-
-Option B can be revisited after Option A ships and stabilizes.
+Pending. Option A is the most pragmatic first step. Option B can be revisited after Option A ships and stabilizes.
