feat: enhance device normalization and classification

- Introduced a new mechanism in EventNormalizer to suppress duplicate events from child nodes of the same physical device.
- Removed the device classification logic from the normalizer and replaced it with a rule-based system using Lua scripts.
- Added support for user-defined device rules in Lua, allowing for flexible device naming based on various conditions.
- Updated the state engine to handle device rules and resolve device names before dispatching events.
- Modified the installation script to set up default configuration files for the daemon and Lua modules.
- Improved the handling of systemd user services to dynamically set the ExecStart path based on the installation directory.
