awesome-ios-sim: Turn iOS Simulator state into versionable code

# Introduction In DeepSeek Harness (DSH), integrating an iOS simulator with an agent typically involves opening a shell for the agent to directly call `xcrun simctl`. The practical challenges of this approach are significant: environment configurations are scattered across scripts and undocumented `defaults` commands, making test environments difficult to reproduce. Additionally, the model is exposed to an untyped and unsafe shell interface, making it difficult to audit what was changed and in what order. `qubyyang/awesome-ios-sim` solves this problem. It does not add new simulator capabilities but encapsulates "changing simulator state" into a fixed process: ```text profile + current snapshot ```
