Add pyproject.toml for Custom Node Registry

[haohaocreates]

Hey! My name is HaoHao and I'm from comfy-org! We would love to have you join the Comfy Registry, a public collection of custom nodes which lets authors publish nodes by version and automate testing against existing workflows.

Eventually, the registry will be integrated as a backend for the UI-manager where all nodes will go through a security scan. Nodes that pass these checks will have a verification flag (✅) beside their name on the UI-manager. Feel free to read up more on the registry here

Action Required:

• Go to the registry. Login and create a publisher id (everything after the @ sign on your registry profile).
• Add the publisher id into the pyproject.toml file.
• Merge the separate Github Actions PR, then merge this PR.

If you want to publish the node manually, install the cli by running pip install comfy-cli, then run comfy node publish

Otherwise, if you have any questions, please message me on discord at haohao_81202 or join our server!
