refactor(memory): rename workflow.target -> params, type -> name

The Workflow STM component stored an active workflow as
{type, target, stage, started_at}. Now that start_workflow takes a
workflow_name and a params dict, those keys match what they actually
hold:

  type   -> name    (the YAML workflow name, e.g. media.organize_media)
  target -> params  (the dict passed to start_workflow)

ShortTermMemory.start_workflow parameters renamed accordingly. All
consumers (prompt builder workflow scope + STM context, start/end
workflow tools) updated.
