fix(ci): prevent nightly tests from using npm stable instead of verdaccio snapshot

[jacekradko]

Summary

Fixes nightly e2e test failures where tests were getting @clerk/[email protected] (stable) instead of locally-built snapshot packages from verdaccio.

Root Cause:

• verdaccio.install.yaml had proxy: npmjs for @clerk/* packages
• Snapshot packages are published with snapshot dist-tags, not "latest"
• When tests requested @clerk/nextjs@latest, verdaccio couldn't find it locally and proxied to npm
• npm returned stable 6.x which doesn't have the Show component (v7 only)
• This caused the misleading error: "Export Show doesn't exist in target module"

Changes:

• Remove proxy: npmjs for @clerk/* in verdaccio.install.yaml to prevent npm fallback
• Remove E2E_CLERK_JS_VERSION: "latest" from nightly workflow to use '*' (via linkPackage()) which matches any version including snapshots

Test plan

• Nightly workflow should now correctly use snapshot packages from verdaccio
• The Show component import should resolve correctly with the v7 snapshot

Summary by CodeRabbit

• Chores
  • Updated CI workflows and snapshot/versioning steps to improve build consistency and snapshot testing.
  • Adjusted local registry and publish settings to ensure locally published packages are used during testing.
  • Removed an unused package from internal publish/version reporting and from a test preset dependency graph.
  • Minor integration and environment variable handling tweaks; no user-facing changes.

📝 Walkthrough

Walkthrough

Added a new empty changeset file and updated CI and registry configs. The nightly-checks workflow gained a "Version packages for snapshot" step, verdaccio publish now uses the latest tag, and explicit environment variables for the JS and UI e2e packages were replaced by comments/wildcard linkPackage usage; multi-line pnpm install/init scripts were introduced. The verdaccio registry config removed the proxy setting for clerk/* packages. A public package entry (clerk/types) was removed from a CI action and its dependency was removed from the nuxt integration preset.
