feat(pipeline): add configuration and hooks for pipeline execution

- Introduce `IPipelineExecutorConfig` to enable customizable pipeline behavior
- Add `IPipelineHooks` interface for tracing and monitoring lifecycle events
- Define callback types for pipeline start, step execution, and completion
- Export new types and interfaces for broader integration within the system
