feat: add --add-ons option in `sv create`

[hyunbinseo]

It is currently impossible to include add-ons without interactive user input.

pnpm dlx sv create --template minimal --types ts --no-install ts

create-svelte provided API, so the following was possible:

/** @param {'checkjs' | 'typescript'} type */
const generateOptions = (type) =>
  /** @type {const} */ ({
    types: type,
    name: `svelte-kit-${type}`,
    template: 'skeleton', // or 'default' or 'skeletonlib'
    prettier: true,
    eslint: true,
    playwright: false,
    vitest: false,
  });

Workaround

pnpm dlx sv create --template minimal --types ts --no-install --no-add-ons ts
pnpm dlx sv add --no-install --cwd ts eslint prettier

We've discussed this before when we were implementing both create and add (though, i'm having a hard time finding the conversation here, so it may have been in private), but the 'workaround' is the intended solution:

sv create . --template minimal --types ts --no-install --no-add-ons && sv add --drizzle --lucia

Since create and add are two very different tasks, they can easily be combined with a simple && operator if you really want a single-liner.

create-svelte provided API, so the following was possible:

A comparable api for this is still being worked on. For now, sv exports create and installAddon, but they're api is not finalized and can change at any moment.

Closing because of the reasoning above.
