fix: render remote query redirects across layout boundaries

[svelte-triage-bot]

What

• avoid awaiting redirect navigation from a remote query that may be blocking component settlement
• add regression coverage for redirects that leave the query page’s layout boundary
• add a patch changeset

Awaiting _goto from the query caused a cycle: the query blocked the pending component update while the redirect navigation waited for that update to settle. The URL and page state changed, but the redirected component tree was not committed.

Fixes #16974

Testing

• focused remote-query redirect tests in development mode: 3 passed
• focused remote-query redirect tests in production-build mode: 3 passed
• pnpm -F @sveltejs/kit test:unit
• pnpm -F test-async check
• pnpm lint
• pnpm check
• original StackBlitz reproduction linked to the local patched package
