Summary

Fixes #527
In 0.42, a Windows stack-overflow fix moved spotatui’s runtime off the main thread on every platform. That left macOS pumping a worker thread’s run loop, so media-key commands went to Apple Music. This change restores main-thread execution on macOS. Windows config not affected.

Summary by CodeRabbit

  • Bug Fixes
    • Improved macOS compatibility for media key handling by ensuring the application runs on the required main thread.
    • Prevented potential stack overflow issues in Windows debug builds by running the application with an appropriately sized stack.

📝 Walkthrough

Walkthrough

The binary now uses an async main thread on macOS so media key handling can run on the required thread. Other platforms retain the dedicated thread and Tokio runtime behavior.

Platform-specific runtime selection
src/bin/spotatui.rs
macOS uses #[tokio::main] and awaits spotatui::run_cli() directly. Non-macOS builds retain the dedicated 16 MiB stack thread and panic propagation.

The runtime fix targets macOS media-key behavior, but its new entry path is untested; this is a low merge risk with targeted coverage still needed.

Add a macOS regression test for the changed entry path.

src/bin/spotatui.rs now runs run_cli() on the macOS process main thread. No existing test covers this path or asserts macOS media registration and event processing. Add a macOS-gated integration test for this behavior. MacMediaManager::new() handles registration on its dedicated media thread, so the test must not require registration on the process main thread.

The **/*.rs: “Add/adjust tests when changing behavior” guideline applies to this file.
