refactor: phase 2 - modularization of scroll engine
Split monolithic scroll.py into focused modules:
- viewport.py: terminal size (tw/th), ANSI positioning helpers
- frame.py: FrameTimer class, scroll step calculation
- layers.py: message overlay, ticker zone, firehose rendering
- scroll.py: simplified orchestrator, imports from new modules
Add stream controller and event types for future event-driven architecture:
- controller.py: StreamController for source initialization and stream lifecycle
- events.py: EventType enum and event dataclasses (HeadlineEvent, FrameTickEvent, etc.)
Added tests for new modules:
- test_viewport.py: 8 tests for viewport utilities
- test_frame.py: 10 tests for frame timing
- test_layers.py: 13 tests for layer compositing
- test_events.py: 11 tests for event types
- test_controller.py: 6 tests for stream controller
This enables:
- Testable chunks with clear responsibilities
- Reusable viewport utilities across modules
- Better separation of concerns in render pipeline
- Foundation for future event-driven architecture
Also includes Phase 1 documentation updates in code comments.
