Pull request overview

This PR updates the monorepo’s frontend/tooling stack to Vite 8 and aligns related build/test infrastructure (Vite configs, declaration generation, banner injection, and Node/ESM path handling) across multiple packages.

Changes:

• Bump Vite to ^8.2.1 across packages and refresh the lockfile accordingly.
• Replace vite-plugin-banner / vite-plugin-dts with a shared internal banner plugin and unplugin-dts.
• Adjust Node/ESM behavior and build/test configs (e.g., import.meta.dirname, remote-core DOM shim ordering, Vitest browser config re-exports).

packages/react-tunnel/vitest.config.ts:4

• The import specifier uses a trailing slash ("../core/") which may resolve differently than "../core" (especially under ESM directory-resolution rules) and is inconsistent with the other updated config imports. This can cause Vitest to fail to resolve the module entry depending on the resolver.

import { vitestBrowserTestConfig } from "../core/";

packages/react-tunnel/vite.build.config.ts:28

• preserveUseClientBanner intentionally returns an empty string for index.mjs and only matches .mjs filenames. In this build config there is a single index entry and no preserveModules / custom entryFileNames, so the post-banner will very likely never emit the "use client" directive anymore (regression vs the previous vite-plugin-banner logic that covered the entry).

      rolldownOptions: {
        output: {
          postBanner: preserveUseClientBanner,
        },
      },

packages/components/package.json:3

• This PR changes multiple package versions from 0.2.0-alpha.1032 down to 0.2.0-alpha.1026, while other workspace packages (e.g. packages/typescript-config/package.json) remain on 0.2.0-alpha.1032. That leaves the monorepo versions inconsistent and also looks like an accidental downgrade unrelated to the Vite 8 bump.

  "version": "0.2.0-alpha.1026",
