refactor(package): rename to dm_imu and restructure directories

Renamed package from dm_imu_pkg to dm_imu across PKG-INFO, egg-info files,
and directories. Updated CMakeLists.txt, __init__.py, and top_level.txt to
reflect new structure. Bumped gradio version from <5.0 to <6.0 in
dependencies. This refactoring improves naming consistency and streamlines
the package layout for better maintainability.
