fix(rsc): pre-include React peers in client env optimizeDeps

The client environment only had `react-dom/client` and the React
Server DOM browser entry in `optimizeDeps.include`. React itself
and crawled React-peer packages were discovered lazily as the
browser requested modules, which re-runs the optimizer mid-load
and changes the `?v=` hash on already-served chunks. The browser
ends up with two distinct React module records, and `'use client'`
libraries that synchronously call hooks in providers hit the wrong
dispatcher (`React.H` is null), throwing `Invalid hook call`.

Mirror the SSR/RSC env behaviour by including `react`,
`react-dom`, `react/jsx-runtime`, `react/jsx-dev-runtime`, plus
the React-peer packages from `crawlFrameworkPkgs`. Filter that
list to packages with a client-resolvable entry so server-only
React peers (e.g. `@vitejs/test-dep-client-in-server`) don't
break dep optimization.
