Proposal: Add ability to quickly run starter project on Val Town

[charmaine]

Hey there!

I’d love to propose adding a Val Town badge to the README so new users can spin up a client for their own Bluesky bot in just one click.

I work at Val Town and it would mean the world to us to contribute to Bluesky's developer community. Val Town lets users run scripts and cron jobs without additional configurations or backends / servers, which seems perfect for examples like this.

Proposed badge in README:

In action:

Why this could be helpful:

1. Gives users instant access to a working example.
2. Lets them fork and customize the example in a single click.
3. Helps avoid local development headaches (like node/npm issues) so users can focus on your API instead.

We recently did this with Steel's Cookbook and they were super excited about it, so we thought it'd be awesome to bring the same experience to Bluesky.

We’re happy to help maintain this starter on Val Town as your API evolves, or you’re welcome to fork it so you have full control.

This PR should be good to go as-is, but we’d love to hear your thoughts! 😊
