Claude Code Review

Critical Issue: External PR workflows will break

This PR reverts from pull_request_target to pull_request, which will break CI for external contributors:

The Problem

1. pullrequest.yml requires CLOUDFLARE_API_TOKEN and CLOUDFLARE_ACCOUNT_ID for E2E tests (.github/workflows/pullrequest.yml:138-139, :164-165)
2. pkg-pr-new.yml requires DOCKER_HUB_USERNAME and DOCKER_HUB_ACCESS_TOKEN (.github/workflows/pkg-pr-new.yml:72-73)
3. claude-code-review.yml requires ANTHROPIC_API_KEY (.github/workflows/claude-code-review.yml:35)

With pull_request, external forks cannot access repository secrets, so these workflows will fail immediately for any external contributor.

Two Options

Option A: Keep pull_request_target with environment approval (previous approach)

• Pros: Workflows work for external contributors after manual approval
• Cons: Requires manual gate-keeping

Option B: Accept broken external contributor workflows (this PR)

• Pros: No manual approval needed for internal PRs
• Cons: External contributors can't run CI at all - maintainers must checkout and test locally

Recommendation

If the project accepts external contributions, revert this change and keep the external-pr environment approval system. It's the only way to safely give external PRs access to secrets.

If external contributions are rare/not expected, this PR is acceptable but should document that external PRs won't have CI feedback.
