Master migrated to ESM after this branch was created, so the CommonJS test failed to load on the merge commit.

Review feedback: the download field now always carries the delta and the deserializer applies it against the current state instead of rebuilding the full list first. The previous failed recipe names are passed in so they survive the round trip. The version check moved to the call site.

Covers the empty response, the full list without a snapshot, the delta with a snapshot, and the IPC registration.

Lua includes its current cleared recipe list in the download request. The instance plugin diffs it against the stored list and sends back the names to add and remove instead of the full list. Lua rebuilds the full list from the snapshot kept in the download record and runs the existing deserializer, so the end state is unchanged.
Also stop the serializer from appending to the stored failed recipe list in place, which grew the list on every upload without a download in between.
