wrangler only binds the worker port on 127.0.0.1, so requesting `localhost` (which resolves to ::1 first) could connect to another wrangler's inspector that happened to get the same port number on ::1, failing with a 500 "Not yet implemented". Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

I think it is better if we keep it and fix it by adding this: https://github.com/getsentry/sentry-javascript/pull/25508/changes#diff-b2cf573a93bbfe5d7150cb2b0b02bb40a6e35dc9f7ad1031cdf018287cf317f4 wdyt? |

Fixes a flaky Cloudflare integration test failure like
Expected request to "/queue/send" to succeed, but got a 500 response: Not yet implemented.wrangler/workerd binds the worker port only on
127.0.0.1(IPv4 and IPv6 listeners each get their own port-0 assignment). The runner requestedhttp://localhost:<port>, which Node tries on::1first — normally refused, then falling back to IPv4. But when another wrangler's inspector happens to hold[::1]:<same port>, the request lands there, and workerd's inspector answers any unknown path with 500 "Not yet implemented". Requesting127.0.0.1directly avoids the ambiguity; thestartSpantest's host/URL assertions are updated accordingly.🤖 Generated with Claude Code
