+- Kept domain-specific structured-data parsing and diagnostics inside Data
+  Tools while removing its duplicate worker lifecycle implementation.
+- Added explicit modular import/export adapter registries for every supported
+  structured-data format.
+- Added bounded sample-based JSON Schema inference with field presence,
+  nullability and exact numeric-representation evidence.
+- Added immutable RFC 6901 structural edits with a reviewed source-format
+  preview and mandatory acknowledgement of known serialization loss.
