[1.0.2] - 2026-07-16

Fixed

• Neo4j code property was silently null (Tests are failing upon migration to codeanalyzer 2.1+ #104): schema v2 removed the per-node code
  field (source lives once on PyModule.source, sliced by spans), but the Neo4j projection
  still read the old field — every :PyClass/:PyCallable node was written without code,
  deadening the py_code_fts fulltext index and the SDK's RETURN c.code queries. The
  projection now derives code at projection time by slicing the owning module's source
  with the node's utf-8 byte span. Regression gate:
  test_projected_code_property_is_the_module_source_span_slice.
