Support exchanging way nodes via comfort0

[aharvey]

In my mapping use case, I way A which I want to retain in OSM with full history, and way B which I want to delete from OSM, however I'd like way A to drop/delete all of it's original nodes, and instead use the nodes from way B.

In other words swap the geometry from way B to way A.

More Tools > Replace Geometry doesn't work since both ways are already in the database.

I thought I could do this with level0, just move the nodes from way B to way A and then delete the way A nodes, but,

1. when I did that, nothing happened
2. when I tried to use "-way" to remove a way with level0, I just got an error that an unexpected exception occured.

for my specific use case I found asking an LLM to build a plugin worked better ​https://github.com/andrewharvey/josm-replace-nodes, but it would still be nice to have the ability to do this via level0 too.

I recently had the same use case with two building outlines and solved it by drawing a new way using the Follow line action so that I could use the Replace geometry action later. Of course more manual actions, but good enough for this rare case.
