feat: Upgrade to validator v2.0.0 with beta testnet real keys

Major upgrade from v1.0.0 to v2.0.0 with complete restructure:

Features:
- One-command validator setup (setup.sh)
- Automated dependency checking (Git, Rust, Node.js, build tools, Nginx)
- Shared Pezkuwi-SDK build (single build for all validators)
- Single DKSweb frontend with auto-update from GitHub
- 8 beta testnet validators (corrected from 10)
- Real validator keys from currently running beta testnet
- Helper scripts (start.sh, stop.sh, status.sh, logs.sh)
- Systemd service management
- Nginx-based frontend deployment
- Comprehensive README with usage instructions

Structure:
- validators/validator1-8/ - Individual validator configurations
- Each validator has real keys (BABE, GRANDPA, PARA, ASGN, AUDI, BEEF)
- Port allocation: RPC 9944-9951, P2P 30333-30340
- Validator 1 acts as bootnode

Breaking Changes:
- Removed docker support
- Removed old installation scripts (linux/windows)
- Removed LICENSE file
- Complete restructure of directory layout
