document deploy script usage in readme

Add clear documentation showing:
- deploy.sh with no arguments uses default /opt/jrunner location
- deploy.sh with argument deploys to custom location for testing
- Explain symlink behavior (only for default location)
- Show usage examples for both deployment types
