chore: clean up DMG artifacts and optimize release build

- Remove generated DMG file and temporary build artifacts
- Add release profile optimizations in Cargo.toml:
  - Enable strip to remove debug symbols
  - Set opt-level to 'z' for size optimization
  - Enable LTO (Link Time Optimization)
  - Set codegen-units to 1 for better optimization
