feat: rename agent-install parameters for clarity

- Change --path → --source (much clearer purpose)
- Change --target → --destination (more intuitive)
- Update all code references and documentation
- Add advanced parameter examples to installation guide
- Keep short aliases: -s for --source, -t for --destination

Parameters are now much more self-explanatory:
- --source: where to find the agent YAML
- --destination: where to install the compiled agent
