Adds support for `--duration <seconds>` (and `--help`) to automatically terminate after a set time. Useful for testing, CI, and agent runs where the default infinite loop is problematic. Uses `asio::steady_timer` + `async_wait` for the timeout (unified with the existing signal handling under one io_context). The `process_signals` lambda was restored as it looks nicer. Combines what were 4 incremental commits into one (the separate window refactor from earlier remains). Updated cuber.cpp and includes.
