Removed

• Drop Q.Do method. Modifying the queue while iterating leads to unexpected behavior.

Added

• Add Snapshot method to build a slice from queue contents.
• TryPop and TryPeek variants of Pop and Peek that don't panic.
• Add MuQ, a thread-safe variant of Q with a similar API.

Fixed

• Don't allocate if a queue is filled exactly to capacity.
