WIP: Fix Electron build issues and migrate to @nostr/tools

- Fix TypeScript compilation errors in platform services
- Add missing rotateCamera method and isNativeApp property
- Fix index.html path resolution for packaged Electron apps
- Create separate Vite config for Electron renderer process
- Migrate from nostr-tools to @nostr/tools via JSR for ESM compatibility
- Update all Vite configs to handle mixed npm/JSR package management
- Add comprehensive documentation in BUILDING.md
- Fix preload script path resolution in packaged builds

Resolves build failures with deep imports and missing UI in AppImage.
