a95b24a246 feat(effects): add entropy parameter to effect plugins 
- Add entropy field to EffectConfig (0.0 = calm, 1.0 = chaotic)
- Provide compute_entropy() method in EffectContext for dynamic scoring
- Update Fade, Firehose, Glitch, Noise plugin defaults with entropy values
- Enables finer control: intensity (strength) vs entropy (randomness)

This separates deterministic effect strength from probabilistic chaos, allowing more expressive control in UI panel and presets.

Fixes #32

3a3d0c0607 feat: add partial update support with caller-declared dirty tracking 
- Add PartialUpdate dataclass and supports_partial_updates to EffectPlugin
- Add dirty region tracking to Canvas (mark_dirty, get_dirty_rows, etc.)
- Canvas auto-marks dirty on put_region, put_text, fill
- CanvasStage exposes dirty rows via pipeline context
- EffectChain creates PartialUpdate and calls process_partial() for optimized effects
- HudEffect implements process_partial() to skip processing when rows 0-2 not dirty
- This enables effects to skip work when canvas regions haven't changed

9e4d54a82e feat(tests): improve coverage to 56%, add benchmark regression tests 
- 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
