Adds FeatureTransactions.PropertyUpdate and Session.patchFeature with a
default unsupported implementation. SqlMutationSession implements it as
native SQL on the session's open connection so partial updates see prior
writes from the same transaction:
- main-table SET for scalar/datetime/boolean columns
- geometry via the existing toWkt path: GeoJSON in -> Geometry ->
ST_GeomFromText (with ST_ForcePolygonCW for POLYGON / MULTI_POLYGON),
matching the encoding the INSERT path emits
- VALUE_ARRAY and OBJECT_ARRAY junctions: DELETE existing rows by
parent_pk + INSERT new rows on the same session connection
OBJECT_ARRAY elements with nested OBJECT children, M:N junctions and
FEATURE_REF arrays remain unsupported and are rejected with a clear error.
