Code Review

This pull request updates the versions of vite, vite-plus, and vitest to 0.1.21-alpha.6 in package.json. The reviewer recommends using the catalog: protocol to centralize these versions and points out that pnpm-workspace.yaml, which was mentioned in the PR description, is missing from the commit.

[gemini-code-assist]

The version 0.1.21-alpha.6 is hardcoded multiple times in this file (lines 75, 76, 79, 103, and 104). Since the PR description mentions updating pnpm-workspace.yaml catalogs and the project uses pnpm 10, it is recommended to use the catalog: protocol to centralize these versions and avoid redundancy.

Furthermore, pnpm-workspace.yaml is explicitly mentioned in the description but is not included in the changes. If you updated the catalogs, please ensure that file is committed to this pull request.
