- Add EffectPlugin ABC with @abstractmethod decorators for interface enforcement - Add runtime interface checking in discover_plugins() with issubclass() - Add EffectContext factory with sensible defaults - Standardize Display __init__ (remove redundant init in TerminalDisplay) - Document effect behavior when ticker_height=0 - Evaluate legacy effects: document coexistence, no deprecation needed - Research plugin patterns (VST, Python entry points) - Fix pysixel dependency (removed broken dependency) Test coverage improvements: - Add DisplayRegistry tests - Add MultiDisplay tests - Add SixelDisplay tests - Add controller._get_display tests - Add effects controller command handling tests - Add benchmark regression tests (@pytest.mark.benchmark) - Add pytest marker for benchmark tests in pyproject.toml Documentation updates: - Update AGENTS.md with 56% coverage stats and effect plugin docs - Update README.md with Sixel display mode and benchmark commands - Add new modules to architecture section
