test(plugin): pin a composer-normalize fixture and compare its listing

The pinned plugin and its real dependency tree (nine packages, fetched by
commit and verified by tree hash into the git-ignored ext/) install under
both implementations, and the list/help renderings of the plugin-provided
normalize command must match upstream byte for byte. The execution
comparison is written but ignored: NormalizeCommand builds a second,
in-process Composer instance, and the worker's proxy stubs reject native
construction of the classes that path instantiates. Stale comments about
the missing worker-side application are updated to the current facts.
