Implements a form state task queue. This will prevent onChange handlers within the form component from processing unnecessarily often, sometimes long after the user has stopped making changes. This leads to a potentially huge number of network requests if those changes were made slower than the debounce rate. This is especially noticeable on slow networks. Does so through a new `useQueue` hook. This hook maintains a stack of events that need processing but only processes the final event to arrive. Every time a new event is pushed to the stack, the currently running process is aborted (if any), and that event becomes the next in the queue. This results in a shocking reduction in the time it takes between final change to form state and the final network response, from ~1.5 minutes to ~3 seconds (depending on the scenario, see below). This likely fixes a number of existing open issues. I will link those issues here once they are identified and verifiably fixed. Before: I'm typing slowly here to ensure my changes aren't debounce by the form. There are a total of 60 characters typed, triggering 58 network requests and taking around 1.5 minutes to complete after the final change was made. https://github.com/user-attachments/assets/49ba0790-a8f8-4390-8421-87453ff8b650 After: Here there are a total of 69 characters typed, triggering 11 network requests and taking only about 3 seconds to complete after the final change was made. https://github.com/user-attachments/assets/447f8303-0957-41bd-bb2d-9e1151ed9ec3
