Add Tauri framework development skill

Created comprehensive Tauri skill for building desktop and mobile
applications with Rust backend and web frontend.

Skill Content:
- Complete Tauri 2.0 framework coverage
- Cross-platform development (Windows, macOS, Linux, iOS, Android)
- IPC communication patterns (commands, events, bridges)
- Security best practices (capabilities, permissions, CSP)
- Native API integration (system tray, notifications, file system)
- Build and distribution guidance (code signing, auto-updater)

Files Created:
- skill.md - Main skill with 6 slash commands
- templates/
  - tauri.conf.json - Config template with all options
  - capabilities/default.json - Basic permissions
  - capabilities/fs-full.json - File system access
  - capabilities/network.json - Network permissions
  - src-tauri/commands/mod.rs - Rust command templates
  - src-tauri/events.rs - Event emission examples
- examples/
  - command-invoking.txt - Frontend command patterns
  - event-listening.txt - Event handling patterns
  - plugin-usage.txt - 10+ plugin examples (fs, http, dialog, etc.)
  - mobile-setup.txt - iOS/Android development guide

Slash Commands:
- /tauri-init - Initialize new Tauri project
- /tauri-add-plugin - Add Tauri plugin
- /tauri-build - Build for specific platform
- /tauri-capability - Create permission capability
- /tauri-ipc - Design IPC interface
- /tauri-native - Add native feature

Integration:
- Uses rust-patterns for backend code quality
- Integrates with react-dev, vue, svelte for frontend
- Leverages architecture skill for system design
- Uses test-driven-development for testing

Credits:
- Proper attribution to Tauri Team and The Commons Conservancy
- Links to official documentation and community resources
