* fix(doctor): gate cross-state-dir legacy imports behind explicit doctor opt-in
A gateway or CLI command started with OPENCLAW_STATE_DIR pointing at a
non-default directory used to import legacy files FROM the default
~/.openclaw state dir (exec-approvals.json, plugin-binding-approvals.json)
and archive the originals with a .migrated suffix. Any isolated, test, or
staging run on a host with production state silently captured and archived
the production files.
Cross-state-dir imports now run only with the new crossStateDirImports
opt-in: openclaw doctor --fix (or an interactive doctor confirm) performs
the import; the implicit CLI/gateway preflight leaves the default dir
untouched and emits a notice pointing at doctor instead.
* test(doctor): include notices in legacy-state detector mocks
