Add knip configuration for node-renderer package

The knip linter was reporting react-on-rails-pro as an unused dependency
in the node-renderer package. While it's not directly imported in source
files, it's a runtime dependency needed for the package to function.

Changes:
- Added packages/react-on-rails-pro-node-renderer workspace to knip.ts
- Configured entry points (index.ts, server.ts)
- Added ignoreDependencies for:
  * react-on-rails-pro (runtime dependency)
  * @honeybadger-io/js (dev/test dependency)
- Ignored lib/** (build output) and tests/fixtures/**

This resolves the "Unused dependencies" error in CI linting step.
