SvelteKit 3 supported; orchestrion covers AWS, LangChain, Mongoose

Important Changes

• feat(sveltekit): Add support for SvelteKit 3 (#22264)

  The SvelteKit SDK now supports the pre-release of SvelteKit 3, including client-side pageload and navigation tracing and server-side native tracing, alongside continued SvelteKit 2 support. No Sentry-specific setup changes are required. The SDK detects your SvelteKit version and picks the right implementation automatically.
