Reviewer's Guide by Sourcery

This pull request implements initial iOS support. It introduces a new iOS file selector and initializes the audio session to allow background audio playback. Additionally, it updates the build process to support iOS by using swift-rs to link the necessary libraries and sets the minimum iOS version to 14. Finally, it updates the platform-specific code for media playback and control to include iOS.
