Reviewed by Cursor Bugbot for commit 3fcc2f7. Configure here.
Setting `tunnel: true` (or `{ allowedDsns, basePath, trailingSlash }`) in both
the browser and the server `init` enables the managed tunnel. The browser
resolves it to the DSN-derived same-origin path and sends envelopes as
`application/x-sentry-envelope`, because SvelteKit and Astro CSRF checks reject
a same-origin `text/plain` POST. Server SDKs keep their own envelopes going
directly to Sentry and set `_managedTunnel` for their request handlers.
With `debug: true`, the client warns once when a managed tunnel request gets a 403, 404 or 405, pointing at the server side: a meta-framework SDK, an endpoint calling `handleTunnelRequest`, or `allowedDsns`.

There was no way to turn on a managed tunnel from
init, fixed by acceptingtunnel: trueso the browser sends to the DSN-derived path and server SDKs flag that they serve it.The tests check the browser path matches what the server accepts, the new envelope content type, and that server SDKs keep sending their own events directly.
