fix(cli/create): pin packageManager and yarn linker before migrate install

The remote-template migrate flow was breaking on npm/yarn/bun because
`vp install` couldn't honor `--package-manager`:

- `vite_install`'s `prompt_package_manager_selection` hardcodes pnpm
  in CI / non-TTY environments when no `packageManager` field, no
  workspace file, and no lockfile are present. create-vite scaffolds
  without a `packageManager` field, so every non-pnpm path silently
  switched to pnpm at install #1 — leaving the wrong lockfile for
  install #2 and tripping ERR_PNPM_NO_MATCHING_VERSION on CI's local
  tarballs.
- Yarn Berry's default Plug'n'Play stores deps inside .yarn/cache/*.zip.
  `@oxlint/migrate` calls fileURLToPath over zip entries and throws
  MODULE_NOT_FOUND on `@eslint/js`.

Before install #1 in the migrate-gated branches (standalone + monorepo):

- Call `setPackageManager(fullPath, downloadPackageManager)` so
  `vp install` picks up the `--package-manager` choice from the field.
- For yarn, write a minimal `.yarnrc.yml` with `nodeLinker: node-modules`
  so the install produces a classic `node_modules/` that
  `@oxlint/migrate` can resolve.

Export `setPackageManager` from migrator.ts for reuse from create/bin.ts.

Verified end-to-end locally: all four package managers
(pnpm / npm / yarn / bun) now migrate `vite@9.0.5 --template react-ts`
cleanly — eslint.config.js removed, `.oxlintrc.json` merged into
vite.config.ts, packageManager pinned to the chosen PM. Drop the CI
matrix `exclude` that previously scoped this entry to pnpm.
