feat(records): add list (filter) endpoint with read data classes

Add RecordsAPI.list, a cursorless POST to /streams/{streamId}/records/filter
returning a RecordList (max 1000 records). Introduces the records read model:

- Record / RecordList read data classes (clean CogniteResource, no RecordId
  multiple-inheritance; RecordList carries optional `typing`).
- TimeRange (gte/gt/lte/lt) for last_updated_time and RecordSourceSelector for
  source/property selection; reuse the data-modeling Filter DSL, InstanceSort,
  and TypeInformation.
- Add a READ op to RecordsConcurrencyOperation + a read semaphore to the
  records concurrency config (reads no longer borrow the write semaphore).

Also register the records API module in the docstring-example doctest runner.
target_units is intentionally deferred to a follow-up.

+        Returns records matching the given filters, sorted by ``lastUpdatedTime`` unless a custom
+        ``sort`` is given. This endpoint is not cursor-paged: it returns at most ``limit`` records
+        (max 1000). To page over a large time window, issue multiple calls with partitioned

+
+        Args:
+            stream_id (str): External ID of the stream to query.
+            last_updated_time (TimeRange | None): Filter by last-updated time. **Required for
+                immutable streams** (must include a lower bound).
+            filter (Filter | None): Filter expression (see :mod:`cognite.client.data_classes.filters`).
+            sources (Sequence[RecordSourceSelector] | None): Which container properties to return.
+            sort (Sequence[InstanceSort] | InstanceSort | None): Sort specification(s); up to 5.
+            limit (int): Maximum number of records to return (1-1000). Defaults to 10.
+            include_typing (bool): If True, include property type information on the returned
+                list's ``typing`` attribute.
