Merge: src/nitlight: Updated client to avoid crashes on unparsed modules

Since the loader has been upgraded, `nitlight` crashed when using the `--full` option since some modules were recognized by the model but left unparsed, causing the program to crash when fetching the `AModule` from `modelbuilder.mmodule2node`.

This PR fixes the issue by rendering only loaded and parsed modules from the importation chain.
