fixtures: golden payloads for NavigationGpsRequest (VehicleAction 53)

[Bre77]

Adds fixtures/golden/navigation_gps_request.json with four synthetic-coordinate cases, plus a Python test and a TypeScript test that both assert the same encoded bytes and round-trip decode.

• Every case leaves order (tag 3) at its default, so it is absent from the wire.
• No schema change, so no changeset.
• Tests run: the new TypeScript and Python test files only.

📝 Walkthrough

Adds a golden fixture with four navigation GPS request cases. Python and TypeScript tests check field tags, serialized bytes, and decoded values against the fixture.

Changes: Navigation GPS request validation

Layer / File(s)	Summary
Golden fixture and cross-language tests fixtures/golden/navigation_gps_request.json, packages/python/tests/test_navigation_gps_request.py, packages/typescript/test/navigation-gps-request.test.ts	The fixture records four coordinate cases and expected wire-format bytes. Python and TypeScript tests check field tags, serialized bytes, and decoded coordinates and order values.

Merge Risk: 🔵 Low · up to 802dd

The tests may miss a future regression that drops an empty navigation request. Adding presence assertions would close this narrow gap; the PR is otherwise mergeable.

39-41: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Assert nested-message presence in both round-trip tests.

The origin fixture contains a present, empty navigationGpsRequest. The current assertions do not check presence. TypeScript replaces an absent request with zero values through ?. and ?? 0. Python reads default-valued fields from an absent submessage accessor. A decoder that drops the nested message can therefore pass while the encoded bytes still match.

Add presence assertions before comparing the fields. This is additional coverage for the intended round-trip contract, not a current functional failure.

Suggested TypeScript fix

     const decoded = Action.decode(encoded);
-    assert.equal(decoded.vehicleAction?.navigationGpsRequest?.lat ?? 0, c.payload.lat);
-    assert.equal(decoded.vehicleAction?.navigationGpsRequest?.lon ?? 0, c.payload.lon);
-    assert.equal(decoded.vehicleAction?.navigationGpsRequest?.order ?? 0, c.payload.order_number);
+    const request = decoded.vehicleAction?.navigationGpsRequest;
+    assert.ok(request);
+    assert.equal(request.lat, c.payload.lat);
+    assert.equal(request.lon, c.payload.lon);
+    assert.equal(request.order, c.payload.order_number);

Suggested Python fix

                 decoded = Action.FromString(encoded)
+                self.assertTrue(
+                    decoded.vehicleAction.HasField("navigationGpsRequest")
+                )
                 request = decoded.vehicleAction.navigationGpsRequest
