chore: keep only the working support channel in package READMEs

[polaz]

Summary

The per-package READMEs (coordinode, langchain-coordinode, llama-index-coordinode) still linked GitHub Sponsors and Open Collective, neither of which is set up. They now show the maintainer's wallet only, matching the root README.

Testing

Text only; no code change.

Closes #92
