Refactored MIDI message classes to improve modularity and flexibility, introducing separate classes for distinct MIDI message types. Updated `build.gradle.kts` version to `0.2.0` to reflect these changes. Removed `.idea/.name` file as part of cleanup.
Removed old database-related implementations (`Database`, `Migrations`, and `Main`) and replaced them with a new focus on MIDI message handling. Updated project metadata, introduced multiplatform `MidiMessage` classes, and added publication/CI setup for Maven compatibility.
