Isolate demo project to its own pnpm workspace

[carbonrobot]

Isolate demo project to its own pnpm workspace and fix the TS build errors.

• Uses Vite as the demo server and hot reload
• Moves all the dependencies to the new workspace and out of root
• Updates all the imports to reference victory (this creates some duplicates, but we are eventually migrating all these files so this is ok for now)
• Modifies the start command to separate running and package watch mode.

// start demo and watch demo files only
$ pnpm start

// start demo and watch packages and demo files
$ pnpm start:dev
