dita_v2: reconcile SOA — vendored thread-safety hardening ∪ venue plane

Browse Source 
3-way merge (base=pre-venue-plane upstream, ours=violet-main vendored hardening,
theirs=upstream venue plane): RLock atomic-snapshot wrapping (account.py,
real_control_plane, real_zinc_plane), lazy __getattr__ imports (__init__),
account-core test coverage — merged with venue_region telemetry. Zero conflicts;
all files AST-verified. Ends the two-way vendor drift found in
DITAV2_SOA_SURVEY_20260702 §5 / UV_DITAV2_SOA_VERDICT_20260703.
