Reflect this session's implementation work in the Transport (#24)
component spec:
- New 'CLI' section covering bundle export / preview / import
commands, the base64-over-JSON wire format, the 200 MB request-body
cap, and the 5-minute per-command timeout. Authorization table +
Interactions section updated to mention ManagementActor handlers.
- Import wizard nav placement corrected from Design to Admin (already
the case in code; the spec lagged).
- Blocker-scan heuristic boundaries documented under Import Flow:
the '.' skip, the DataSourceReference exclusion, and the
KnownNonReferenceNames denylist. Both DetectBlockersAsync and
RunSemanticValidationAsync Pass 1 share the filter.
