[wrangler] Clean up preview deploy output

[yomna-shousha]

AI generated.

Summary

• Replaces the boxed wrangler preview success output with a compact linear summary.
• Removes config source markers, observability/logpush status, and preview bindings from preview success output.
• Adds CI pull request metadata annotations and prints a Pull Request link when detected.
• Groups deploy custom domains under Custom Domains: and removes internal custom-domain/previews state annotations.

Examples

wrangler preview now prints:

Preview: test-preview (new)
Preview URL: https://test-preview.test-worker.cloudflare.app

Deployment ID: deployment-id-123
Deployment URL: https://abc12345.test-worker.cloudflare.app

Pull Request: https://gitlab.example.com/acme/worker-project/-/merge_requests/13

wrangler deploy custom domains now print:

Deployed test-worker triggers (TIMINGS)

Custom Domains:
  api.example.com

Notes

• Uses truthy CI env fallbacks so empty env vars do not mask later values/defaults.
• Retries preview deployment without PR/repository annotations if the API rejects them as unsupported.
• Addresses review comment: [wrangler] Add PR metadata to preview deployments #14966 (comment)

Testing

• pnpm exec oxfmt --check packages/deploy-helpers/src/preview/api.ts packages/deploy-helpers/src/preview/shared.ts packages/deploy-helpers/src/preview/preview.ts packages/deploy-helpers/src/triggers/publish-routes.ts packages/deploy-helpers/src/triggers/deploy.ts packages/wrangler/src/__tests__/preview.test.ts packages/wrangler/src/__tests__/deploy/routes.test.ts .changeset/pretty-preview-output.md
• pnpm --filter @cloudflare/deploy-helpers check:type
• pnpm --filter wrangler type:tests
• NODE_OPTIONS="$(node scripts/node-options-for-tests.js)" pnpm exec vitest run src/__tests__/preview.test.ts src/__tests__/deploy/routes.test.ts
