Core concepts

• Steps are Prefect tasks defined using @step or specialized step decorators.
• A TestSequence is a Prefect flow that aggregates and executes multiple steps, tracking their states.
• ptf_context is a shared runtime context that provides access to globals, locals, results, and current_step.
• SequentialProcessModel orchestrates execution callbacks in a fixed lifecycle: pre_uut -> main_sequence -> post_uut -> report -> database_logging.
• The main output of the process model is stored in both main_results and main_result for backward compatibility.
