… publish order

Parse string remotes with name@url semantics so federation externals bypass works for
mf-manifest-based remotes. Update pkg.pr.new workflow to publish fixed-group packages
in dependency order, preventing stale internal preview dependency links.

Co-authored-by: Cursor <cursoragent@cursor.com>
Use SHA-based pkg.pr.new links in PR comments to avoid stale PR-number alias
resolution for internal preview dependencies in downstream installs.

Co-authored-by: Cursor <cursoragent@cursor.com>
Let federation() accept ModuleFederation options and apply ModuleFederationPlugin
internally with target-aware defaults for node and browser runtimes.

Co-authored-by: Cursor <cursoragent@cursor.com>
Refresh pnpm-lock.yaml so pkg.pr.new CI can install with frozen lockfile
after adding rstest-plugin dependencies.

Co-authored-by: Cursor <cursoragent@cursor.com>
Add rstest demo apps for rspack, rsbuild adapter, and rslib adapter with
node/browser harnesses, and add a dedicated e2e-rstest workflow for CI coverage.

Co-authored-by: Cursor <cursoragent@cursor.com>
Use TCP port probes for local server readiness checks instead of HTTP fetch polling.
Add minimal read-only workflow permissions to the e2e-rstest CI job.

Refresh pnpm-lock.yaml for this branch so checkout-install and publish-preview
no longer fail with ERR_PNPM_OUTDATED_LOCKFILE.
