feat: workflow elements

[cwandev]

Closes #21

[peoray]

@cwandev not sure what the issue is but I can't collapse the other sub folders except I manually navigate to a component and then the preview and code component does not display.

is this behavior only on my machine?

fwiw, I think it's best if we reduce scope for PRs

[cwandev]

@peoray I guess you might be running into something like this (please check your console):

node_modules/dayjs/dayjs.min.js' does not provide an export named 'default'

This issue sometimes occurs with Nuxt v3 — see this discussion.

Although Daniel Roe fixed it, it can still happen in certain environments.

In this PR, I’ve added the dayjs to vite.optimizeDeps.include to temporarily fix the issue.

We might need to wait until shadcn-docs-nuxt supports Nuxt v4 to completely avoid it.

You can try these steps:

1. Go to apps/www
2. Run pnpm install (the www package has a different pnpm setup and node_modules structure)
3. Delete node_modules and reinstall if necessary
4. Run pnpm dev:www again

Sorry this PR includes so many changes — the workflow-related components are tightly coupled.
I think the workflow element might be an exception here. What do you think?

LGTM 👍🏽
