upload_asset_complete

Finalize a multipart upload started by upload_asset. Call this only after every file part has been uploaded to the presigned URLs. Completes the upload on the server and polls until the asset is ready, streaming progress notifications (finalizing → validating → creating asset → ready) while it waits. Args: - upload_id: required — returned by upload_asset for multipart uploads - team_id, project_id: required for OAuth callers Returns: the completed asset_id and status when the upload finishes, or a timeout status if the asset is still being processed. Examples: - "Finish the multipart upload" -> upload_id="<upload_id from upload_asset>" - "Complete upload after PUTing all parts" -> call upload_asset_complete once every part upload succeeded Don't use when: upload_asset already returned an asset_id from the inline base64 path.
