CVE-2026-82743: Elixir Task Yield Zero Timeout Busy Spin
Calling `Task.yield/2` with a 0ms timeout performs a non-blocking check. When executed in a loop or recursive polling function without blocking or sleeping, it causes busy-spinning that exhausts BEAM scheduler CPU resources. Use `Task.yield_many/2` with a blocking timeout or an appropriate synchronization mechanism.
