LG! One last thing: can you add a changeset with a patch bump on baseten plugin?

[jebentier]

@toubatbrian Thank you for getting this reviewed and merged, I noticed that the @livekit/agents-plugin-baseten isn't releasing yet. Is there something else that we should do in order to get the package releasing for use?

[toubatbrian]

Hey @jebentier, the issue might be that the package.json is marked as "private": true in the original PR, which causes both npm and Changesets to skip publishing it.

I'm currently on time off and don’t have my laptop with me. Could you help by making a quick PR to remove the private flag? I’ll take care of the remaining CI/CD steps.

Also, please ensure the package.json matches the structure of our other plugins (i.e., includes exports, require, type, etc.) so that module resolution and bundling behave consistently across environments.

Thanks a ton!

Hey @toubatbrian, thank you for taking time to respond while you're off. Here's the PR you requested. I've gone ahead and standardized the package.json and it's build process to match other packages in the plugins directory. Please let me know if there is anything else I can help with, and enjoy your holiday break.
