Function commit_delete 

pub async fn commit_delete(
    storage: &dyn Storage,
    sinks: &WriteSinks<'_>,
    kb: &KbSlug,
    path: &ObjectPath,
    conditionals: ConditionalHeaders,
) -> Result<(), WriteError>

Delete an object idempotently, publish the change and enqueue a best-effort tombstone event — in that order, the one rule after_write follows (D65).
