Add Rule of Thirds grid overlay to camera preview#485
Conversation
Adds a toggleable "Rule of Thirds" grid overlay to the camera preview to help with shot composition. Key changes include: - A `GridType` enum (`NONE`, `RULE_OF_THIRDS`) was introduced to manage grid visibility, allowing for future extensibility. - The grid selection is persisted in DataStore through the `SettingsRepository`. - A toggle button has been added to the Quick Settings panel. - The grid overlay features a fade-in/fade-out animation. The fade-out is handled within a `NonCancellable` context to prevent the animation from being interrupted, which avoids visual flickering. - For iconography, the button uses the standard `Icons.Default.Grid3x3` for the "on" state and a local vector asset (`grid_3x3_off.xml`) for the "off" state.

Code Review
The pull request successfully introduces a toggleable "Rule of Thirds" grid overlay to the camera preview. The implementation includes a new GridType enum, persistence in DataStore, a quick settings toggle button, and a fade-in/fade-out animation for the grid. Unit and instrumentation tests for the new functionality and proto conversions are also included, demonstrating good test coverage. The use of NonCancellable context for the fade-out animation is a thoughtful detail to prevent visual flickering.
