Avoid custom domain prompt for same Worker

[yomna-shousha]

Summary

• Skip the custom-domain replacement confirmation when a modified custom domain already belongs to the Worker being deployed.
• Keep the confirmation for domains owned by another Worker.
• Keep DNS conflict confirmation behavior unchanged.

Context

Repro: deploy a Worker with a custom domain, then add routes[].previews_enabled and redeploy in an interactive terminal. Before this change, Wrangler prompts even though the existing custom domain is already used by the same Worker.

Validation

• pnpm exec oxfmt --check .changeset/fuzzy-dogs-prompt.md packages/deploy-helpers/src/triggers/deploy.ts packages/deploy-helpers/src/triggers/publish-routes.ts packages/deploy-helpers/tests/publish-custom-domains.test.ts packages/wrangler/src/__tests__/deploy/routes.test.ts
• git diff --check
• pnpm --filter @cloudflare/deploy-helpers test run tests/publish-custom-domains.test.ts
• pnpm --filter wrangler test run src/__tests__/deploy/routes.test.ts -t "should not confirm override if custom domain already belongs to this Worker"

Checklist

• Tests included/updated
• Documentation not necessary because: This fixes an unnecessary interactive prompt without changing Wrangler configuration or public APIs.

[GregBrimble]

Maybe add a test for Wrangler Environments too? I get a bit nervous seeing just a bare scriptName floating around. Would like to just make sure we're covering Wrangler Environments too (since their name is dynamic).

[GregBrimble]

Known limitation:

• pnpm --filter wrangler test run src/tests/deploy/routes.test.ts -t "should not confirm override if custom domain already belongs to this Worker" is blocked in this checkout by existing workspace/test setup failures: writeOutput is not a function and clearOutputFilePath is not a function.

Does that work now? Did you need to rebase or something?

[yomna-shousha]

Rebased onto latest main and reran the targeted test. The old setup failure (writeOutput / clearOutputFilePath) is gone.

The test file path is src/__tests__/deploy/routes.test.ts, so I ran:

pnpm --filter wrangler test run src/__tests__/deploy/routes.test.ts -t "should not confirm override if custom domain already belongs to this Worker"

It passes locally. I rebuilt @cloudflare/workers-utils and @cloudflare/deploy-helpers first because the local checkout needed fresh workspace dist output after the rebase.
