Add Mode1Svelte - independent copy of Mode1 for future SvelteKit integration

- Created Mode1Svelte as complete standalone project
- Identical to Mode1 currently (Hono backend + Vite frontend)
- Separate auth-module copy (no dependencies on Mode1)
- Updated orchestrator to default to Mode1Svelte
- Both Mode1 and Mode1Svelte are independent and interchangeable via ModeSwitch
- Ready for gradual Svelte/SvelteKit migration while maintaining API compatibility
