release: 0.3.0-beta.1

Ships JSON API rendering (#3) and the AWS, Google Cloud, and Microsoft Learn
documentation shortcuts (#11) to the beta channel.

Documentation caught up with what the code actually does while it was open:

- Status said the remaining actions land in v0.2, which shipped without them.
  fill, submit, and back are now marked planned in the help and the README,
  a label that cannot go stale the way a version number does.
- llms.txt names the cloud documentation shortcuts and the JSON rendering.

The skill keeps its npx pin on 0.2.0. A pin is what agents actually execute,
so it moves when a release is stable, not when it enters beta.
