Rebrand to Checker Node. Closes #676

[juliangruber]

For #676
Blocks CheckerNetwork/desktop#2049

Renames:

Before	After
Filecoin Station Core	Checker Network Node
Station Core	Checker Node
Station	Checker
CheckerNetwork/core	CheckerNetwork/node
Binary Module	Runtime
Module	Subnet
Station Id	Checker Id

Before, we were using "module" both for binaries like Zinnia and sources like "spark". Since part of the rebrand is to rename module to subnet, I split up this term into runtime and subnet, to avoid any confusion.

After merge

• Rename repo to node
• Publish new major version
• Deprecate old node module https://www.npmjs.com/package/@filecoin-station/core
• Update Station Desktop station core -> checker node desktop#2049

IIRC, we used to have the concept of two kinds of modules - a "trusted module" where we run a precompiled binary provided by the subnet (e.g. Saturn L2 node) and "trustless module" where we run JavaScript/WASM in Zinnia runtime.

I agree with using the term "runtime" for the Zinnia runtime binary (zinniad).

Are trusted subnets something to support in the new naming?

Good point, I've made the decision in this PR that there will only be subnet source files and runtimes. This architecture would be nice as only open source modules can be run. I'm not sure if this decision is correct, but at the same time it makes things easier. Before, we were calling Zinnia a module of Station, and Spark a module of Zinnia (but defined in Station, not Zinnia). This encapsulation was confusing as I was looking over the code.

Since the changes here are relatively simple, and we don't plan to add native / trusted subnets, I suggest we go ahead.

We have agreed to also add migration logic to this repository

The changes look reasonable to me. I have a few comments to discuss, PTAL 👇🏻

LGTM with one comment about README which I think you already resolved.

Great job! 👏🏻

Understood! But: There's no else condition here, and the if body is small. In other cases I would agree with your reasoning and implement it the same way. I can't put into words atm why I find it worse in cases like this. I think mainly that if condition itself is easy to read this way, the proposed one makes me think more
