- Added `pipecat.tasks`, a task-based agent framework folded in from the standalone `pipecat-subagents` package. Tasks inherit from `BaseTask`, share a `TaskBus`, register in a `TaskRegistry`, and exchange typed work via `@job` handlers. `LLMTask` and `LLMContextTask` provide ready-made LLM-driven tasks. `PipelineRunner.spawn(task)` registers fire-and-forget tasks alongside the main pipeline task.
