Clean up ATVM automation examples and standardize status guidance

- keep atvm-automation-examples.md limited to reusable example commands

- move example-file role guidance into AGENTS.md and atvm-automation-guide.md

- document that all ATVM automation run types use the same status display format

- record the status-format rule as a run learning in atvm-automation-runs.md
