perf: optimize bundle size with lazy loading and dependency removal

- Add route-level lazy loading for all pages (Default, Board, Dashboard, etc.)
- Remove gun, webnative, holosphere dependencies (175 packages removed)
- Stub HoloSphereService for future Nostr integration (keeps h3-js for holon calculations)
- Stub FileSystemContext (webnative removed)
- Defer Daily.co initialization until needed
- Add loading spinner for route transitions
- Remove large-utils manual chunk from vite config

Initial page load significantly reduced - heavy Board component (7.5MB)
now loads on-demand instead of upfront.
