Chat could not answer 'какая зона ПЗЗ?' — retrieval loaded only the §22
forecast run (schema 1.0); тер.зона/градрегламент/ЗОУИТ/ЕГРН live in the
analyze-1.0 run and never reached the chat context.
Add get_parcel_context_for_chat: a §19-safe whitelist slice of analyze
(fixed keys AND scalar-only values — dict/list dropped at the boundary;
ЗОУИТ zone names as a dedicated str-only capped list; no geometry/PII/raw
sub-dicts) merged into a copy of report_dict under 'parcel_context';
expose it via the sixth sectional tool get_parcel_info. Bump chat_system
prompt v2->v3 so the model uses it and no longer treats the parcel's own
ПЗЗ zone as out of scope.
