feat(integration): Complete feature rewrite with pipeline architecture, effects system, and display improvements

Major changes: - Pipeline architecture with capability-based dependency resolution - Effects plugin system with performance monitoring - Display abstraction with multiple backends (terminal, null, websocket) - Camera system for viewport scrolling - Sensor framework for real-time input - Command-and-control system via ntfy - WebSocket display backend for browser clients - Comprehensive test suite and documentation Issue #48: ADR for preset scripting language included This commit consolidates 110 individual commits into a single feature integration that can be reviewed and tested before further refinement.
