feat: Implement plugin system with combat tracker and dice analyzer

- Added `plugin_system_demo.py` to demonstrate basic plugin usage, processing, and analysis.
- Created `CombatTrackerPlugin` for tracking combat statistics including damage and healing.
- Developed `DiceAnalyzerPlugin` for analyzing dice rolls and calculating success rates.
- Introduced `renderer_demo.py` for rendering output in HTML, Markdown, and JSON formats.
- Implemented `rule_system_demo.py` to showcase rule engine capabilities with various examples.
- Established core rule engine functionality in `rules.py` with support for conditions and actions.
- Enhanced base plugin structure in `base.py` to support different plugin types (Processor, Renderer, Analyzer).
- Added custom exception handling in `exceptions.py` for better error management.
- Configured logging setup in `logging_config.py` for improved logging capabilities.
- Created unit tests in `test_rust_core.py` to validate core functionalities and performance.
