Publish Zed Theme Builder as a standalone tool

[ColinMelendez]

Body

What are you proposing?

Publishing the theme-builder tool (https://zed.dev/theme-builder) as a standalone app.

Why does this matter?

It would be useful to be able to:

• use the theme builder offline
• have control over versioning

It is difficult to rely on a web-only design tool that might change it's input/output behavior outside of the control of your workflow.

Are there any examples or context?

Drizzle Studio, Prisma Studio, and Storybook are examples of tools taking a similar approach to what I am thinking of.

Possible approach

A simple way this could be achieved:

1. Bundle the built page with a script that serves it on localhost.
2. Publish it to npm.
3. Users run npx zed-theme-builder and interact with the theme builder from their browser.

Obviously there are many other ways this could be achieved.
