Neutral wording in import docs; portable tool output paths

Import-surface docs and docstrings describe the automation as a
migration script; status-doc references in CHANGELOG/ADR-009/ROADMAP
point at repo files. Screenshot/verify tools write to /tmp/shopdb-shots
(created on import) instead of a machine-specific directory.
