Rename Cloud Runner to Orchestrator (#775)

* Rename "Cloud Runner" to "Orchestrator" across entire codebase

Breaking change: All CloudRunner classes, options, environment variables,
and action.yml inputs have been renamed to Orchestrator equivalents.

- Renamed src/model/cloud-runner/ directory to src/model/orchestrator/
- Renamed all cloud-runner-* files to orchestrator-*
- Renamed all CloudRunner* classes to Orchestrator* (15+ classes)
- Renamed all cloudRunner* properties to orchestrator* equivalents
- Renamed CLOUD_RUNNER_* env vars to ORCHESTRATOR_*
- Updated action.yml [CloudRunner] markers to [Orchestrator]
- Updated workflow files and package.json test scripts
- Updated all runtime strings (cache paths, log messages, branch refs)
- Rebuilt dist/index.js

No backward compatibility layer is provided.

* Remove tracked log/temp files and add to .gitignore

Remove $LOG_FILE and temp/job-log.txt debug artifacts that should
not be in the repository.
