While node.properties function with anything serializeable, the format
for proxyWidgets is not a valid option for type. After great
consideration, all access to and from this value goes through a JSON
serialization and parsing always includes a zod validation step.
This is sturdier to outside misuse, has even lower risk of custom node
breakage, and means that there's now proper type checking at the
boundries of interaction.
Performance was a major concern against this, but the path is quite
cold. I estimate the value of optimization here to be 3-4 orders of
magnitude less important than anything occuring during the draw loop
(like access to proxyWidget elements)
This was needed from an organizational standpoint. For now, it requires
an ugly setTimeout to prevent proxyWidgets from being clobbered during
initialization, but this will be cleaned up later.
This also allows for the proxy widget code to have type checks ignored.
I fully intend to find a functional solution here, but this provides a
migration path where typechecking can be enabled for the rest of the PR
first
Also cleans up type checking on graph change in scripts/app.ts
