Make PipelineTask inherit BaseTask and support bridged pipelines

Browse Source 
`PipelineTask` now extends `BaseTask` so every pipeline task is
also a bus participant. Adds optional `bus`, `bridged`, and
`exclude_frames` parameters: when `bridged` is set, the user's
pipeline is wrapped with `_BusEdgeProcessor` source/sink edges so
frames are mirrored onto the bus. Bridges pipeline lifecycle
events to `start()`/`stop()`, overrides `_handle_task_end` /
`_handle_task_cancel` to drive the pipeline shutdown, subscribes
to the bus in setup, and exposes the `bridged` property to the
registry. Moves `PipelineTaskParams` here and updates the
matching test import.
