Code inspection: Replace 'async' code with 'Task'-return

This inspection reports an async method or local function that only awaits task-returning expressions in tail positions. In this case, async/await adds state-machine overhead without changing behavior, so the code can return the task directly.

Example

                using System.Threading.Tasks;
                class C
                {
                    public async Task<int> GetValue()
                    {
                        return await Task.FromResult(42);
                    }
                }
            

                using System.Threading.Tasks;
                class C
                {
                    public Task<int> GetValue()
                    {
                        return Task.FromResult(42);
                    }
                }
            

Quick-fix

Remove async and return the task directly. The fix also unwraps ConfigureAwait(false) and updates return; in Task-returning methods to return Task.CompletedTask when needed.
