Implement two virtual node patterns for message flow orchestration: - Sequence: Chains listeners in order (A→B→C), feeding each step's output as input to the next. Uses ephemeral listeners to intercept step results without modifying core pump behavior. - Buffer: Fan-out to parallel worker threads with optional result collection. Supports fire-and-forget mode (collect=False) for non-blocking dispatch. New files: - sequence_registry.py / buffer_registry.py: State tracking - sequence.py / buffer.py: Payloads and handlers - test_sequence.py / test_buffer.py: 52 new tests Pump additions: - register_generic_listener(): Accept any payload type - unregister_listener(): Cleanup ephemeral listeners - Global singleton accessors for pump instance Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
