A summary of the changes CodeRabbit can apply:

• Replace the panicking unwrap() with guarded error handling to skip faulty frames and prevent Media Foundation webcam crashes (modify crates/camera-windows/src/lib.rs—line 89) and add documentation (create WEBCAM_CRASH_FIX.md).

• Fix webcam crash by replacing an unwrap panic in crates/camera-windows/src/lib.rs (change let len = unsafe { sample.GetBufferCount() }.unwrap(); to let Ok(len) = (unsafe { sample.GetBufferCount() }) else { return; };) and add a new WEBCAM_CRASH_FIX.md document describing the issue, root cause, fix, testing, impact, and prevention.
