-**BREAKING for Python consumers that read the `level` field.** The Python port

-port emits both fields. Python now matches:
-
-| field      | value                                  |
-| ---------- | -------------------------------------- |
-| `level`    | pino-compatible **numeric** (info = 30) |
-| `LogLevel` | canonical lowercase **string** (`"info"`) |
-
-Migration for Python consumers: anything asserting `record["level"] == "info"`
-should read `record["LogLevel"] == "info"` instead. The numeric codes were
-already defined in `level_to_code()` (trace=10 … fatal=60) and are unchanged;
-they were simply never written to the record.
-
-Also adds `parity-corpus.json` — a committed golden-vector corpus pinning the
-exact `level`/`LogLevel` pair every port must emit for all six levels, asserted
-by the TypeScript (`src/parity-corpus.spec.ts`) and Python
-(`python/tests/test_parity_corpus.py`) suites so drift fails the build.
-Follows the ADR-089 pattern used by `@smooai/audit`.
