Add pyproject.toml for Custom Node Registry

[haohaocreates]

We are building a global registry for custom nodes (similar to PyPI). The registry makes using custom nodes more reliable by reserving globally unique names for each custom node, and supporting semantic versioning.

Here’s some more information on the registry.

Action Required:

• Go to the registry. Login and create a publisher id. Comment it here and we will update the PR (or just merge it and change it yourself).
• Write a short the description.
• Merge the separate Github Actions PR and run the workflow.

If you want to publish the node manually, install the cli and run comfy node publish

Please message me on Discord if you have any questions!

@chrisgoringe Sorry, it's not very clear but publisher names should be lowercase. We treat them as case-insensitive when seeing if there are conflicts.
