Documentation freshness checklist

Review these together whenever a new onboarding-facing workflow or command ships:

1. README.md
2. docs/index.md
3. docs/getting_started.md
4. docs/choose_your_path.md
5. docs/reference/workflow_map.md
6. docs/reference/cli_reference.md
7. the relevant tutorial page
8. the relevant packaged example under src/cranalytics/examples/

Treat this checklist as part of the definition of done for onboarding-facing changes. If one of these surfaces changes, the rest should be reviewed in the same pass.
