feat: publish asset-manifest v1 for Series episode assembly

[IAnMove]

Resultado

Siguiente writer de manifiesto: solo el sidecar de ensamblado de episodios de Series (app/routers/series_assembly.py).

• reutiliza publish_generation_sidecar
• conserva params.seriesId / episodeId / assemblyJobId para la galería
• actor desconocido (unknown); tool = series-assembly
• no se pasa actor; no se inventa
• _remove_assembly_artifacts sigue borrando el sidecar con splitext + .meta.json
• no toca _launch_runtime.py, WanGP, models, agentActions, useStore, i18n ni asset_manifest.py

Verificación local

• pytest test_series_assembly_router + test_series_assembly + test_series_assembly_contract: 14 passed
• architecture_contracts.py: OK
• verify_clean_repo.py: OK

Pendiente de CI. @cursor review sobre este HEAD.

Note

Low Risk
Scoped to sidecar metadata for series assembly outputs; behavior for join/cancel/cleanup is unchanged aside from manifest format.

Overview
Series episode assembly now writes canonical asset-manifest v1 sidecars instead of hand-rolled JSON after FFmpeg joins clips.

A new _write_assembly_sidecar delegates to publish_generation_sidecar with tool="series-assembly", workspace from the job, and the same gallery-facing params (seriesId, episodeId, assemblyJobId). No actor is passed, so origin stays unknown rather than invented. Cleanup via _remove_assembly_artifacts is unchanged.

Tests assert the completed join path and the helper emit SCHEMA_NAME, load correctly through read_asset_manifest, and record origin.tool / origin.actor as expected.
