- Windows launcher (start.bat) for one-click server startup
- Auto-detection of LAN addresses and dependency installation
- Machine-readable JSON output for monitoring and automation

Cli commands:
  serve - Start server with optional config overrides
  status - Display server stats and packet counters
  clients - List connected players
  world time - Set in-game time for all clients
  world weather - Set weather for all clients
  config init - Generate default configuration file

Documentation:
  - Updated docs/setup.md with CLI quick-start guide
  - Added server/README.md with usage instructions
  - Updated changelog and dev-log with test results

Testing: - Verified config generation and loading
