Palette Manager and Flows Site can't cope with a package containing nodes and plugins

There are a couple different things here - the palette manager and the flows site.

Has the flows site ever listed the nodes in your package? Looking at the code, the way you have structured things (by moving the registerType call out of your .html file) means the simple parsing done by the flow library won't find it. That isn't related to the fact you've also got plugins in there.

Hi all, I think this has been raised before.

Yes, you raised an issue here: Palette Manager not showing list of nodes and plugins for a package · Issue #4865 · node-red/node-red · GitHub
And you posted to the forum here: Ongoing bugs in the Manage Palette display

THe PR to fix it is here: Support for a module with nodes and plugins in the palette by GogoVega · Pull Request #4945 · node-red/node-red · GitHub

It needs reviewing, testing and merging - then it'll be available in either 4.0.10 or 4.1
