Support pnpm catalog

[tobynguyen27]

Description

In current Vite+, when running vp add vue with pnpm catalogs configured in pnpm-workspace.yaml, it totally ignores the catalog and add the package with it version directly in package.json.

Since pnpm catalogs feature provide a lot of benefit for packages management (Anthony Fu wrote a blog about it), it will be great if VIte+ does support it.

Suggested solution

• This feature can be toggle by a config in vite.config.ts: pnpm.catalog: boolean or an env var like VP_CATALOG=boolean.

• When running vp add and Vite+ detects a workspace that use pnpm catalog: instead of adding packages with pinned versions, it writes catalog: references into package.json and updates the workspace catalog:

# Given pnpm-workspace.yaml with:
#   catalogs:
#     prod:
#       react: ^18.3.0

vp add react
# → detects react in "prod" catalog
# → writes "react": "catalog:prod" to package.json
# → runs vp install

vp add lodash
# → lodash not in any catalog
# → prompts to select a catalog (or skip)
# → fetches latest version, updates pnpm-workspace.yaml
# → writes "lodash": "catalog:prod" to package.json
# → runs vp install

Thanks for the request!

Vite+ already forwards pnpm catalog flags:

• vp add react --save-catalog
• vp add react --save-catalog-name prod

And when catalogMode: prefer is configured, plain vp add follows pnpm’s native behavior for the default catalog.

It'd be nice if we added an interact TUI:

When execute vp[ add react. It will show a prompt that asks user which catalog should this package added to or creating a new catalog (this TUI is only for workspace which is using name catalogs)
