Description
The following gist shows a semi-complex hierarchy of nested interfaces and records:
https://gist.github.com/pixsperdavid/a1eda8c5742e9c712860d5a93a46cc9b
This fails to build as MemoryPack is generating a partial interface IV1 which is not enclosed in a partial nested interface, causing a duplicate definition.
As I added the nested classes support originally this is my oversight, working on a PR currently to address.

Research direction
Start with the linked gist to reproduce the nested interface and record hierarchy, then inspect the source-generator entry point that emits the partial IV1 interface. Verify the generated declarations preserve their enclosing nested interfaces and build without a duplicate definition.
