refactor: consolidate test-iso.sh and monitor-build.sh into run.sh

- Merged VM testing functions into run.sh (test:iso commands)
- Merged build monitoring into run.sh (monitor command)
- Updated tests to reference ./run.sh test:iso instead of ./test-iso.sh
- Updated documentation (README.md, AGENTS.md, STATUS.md)
- Removed standalone scripts per project cleanup
