test(typegen): pack vinext without rebuilding the shared dist

[james-elicx]

Problem

tests/typegen.test.ts ("installs @vinext/types transitively from packed vinext without Next.js") runs pnpm pack in packages/vinext. That fires vinext's prepack, which runs vp pack with clean: true and wipes packages/vinext/dist for several seconds while it rebuilds.

The unit project runs files in parallel (maxWorkers: 3), and other unit files resolve vinext's package exports from that dist. tests/cache-adapters-build.test.ts ("preserves the CDN response entrypoint through Cloudflare's virtual host entry") imports vinext/server/fetch-handler, and when it lands inside the rebuild window it fails with:

Rolldown failed to resolve import "vinext/server/fetch-handler"

Which files overlap depends on the shard schedule, so a change that only resizes unrelated test files can make this fail on every attempt. It does so on #3465 and every PR stacked above it, which pass on the parent #3463 with the same shard contents.

Fix

Pack vinext with --config.ignore-scripts=true, so the test packs the dist the install already built instead of rebuilding the shared one. Without prepack the README copy no longer happens, so the withPreservedFile wrapper that restored packages/vinext/README.md is removed (the rest of the diff is dedent).

Locally the test still passes, and packages/vinext/dist/index.js keeps its modification time across the run.
