feat: publish asset-manifest v1 for MiniMax images

[IAnMove]

Resultado

Siguiente writer de manifiesto: solo MiniMax Image-01 (app/services/minimax_image_service.py).

• reutiliza publish_generation_sidecar
• conserva las claves de galería (generation_mode, task_id, root_task_id, params, created_at)
• origin.tool = minimax-image; origin.actor = unknown (no se pasa ni se inventa actor)
• no persiste api_key
• generate_image no tiene workspace_id; se omite
• los bytes de la imagen siguen escribiéndose de forma atómica; el sidecar lo escribe el helper
• no toca Director, _launch_runtime.py, WanGP ni otros writers
• archivos únicos: minimax_image_service.py y tests/test_minimax_image_service.py

Verificación local

• pytest test_minimax_image_service + test_asset_manifest: 20 passed
• architecture_contracts.py: OK
• verify_clean_repo.py: OK

Pendiente de CI. @cursor review sobre este HEAD.

Note

Low Risk
Scoped to MiniMax image persistence metadata; behavior for callers is unchanged aside from richer manifest sidecars, with tests covering the new format.

Overview
MiniMax Image-01 now writes generation metadata through publish_generation_sidecar instead of hand-rolling a .meta.json file with json.dump. Image bytes are still saved atomically; only the sidecar path goes through the shared asset-manifest helper.

The sidecar payload keeps the same gallery-facing keys (generation_mode, task_id, root_task_id, params, created_at) and still omits secrets. origin.tool is set to minimax-image with origin.actor left as unknown (no actor is passed from generate_image).

Tests assert the canonical hocuspocus.asset-manifest document via read_asset_manifest, in addition to the existing .meta.json checks.
