Crate bye

bye: graceful shutdown and USR1 zero-downtime upgrade helpers.

• Bye manages a CancellationToken broadcast + a TaskTracker.
• Bye::new_with_signals() listens for TERM/INT/QUIT -> drain, USR1 -> fork+exec self and wait for child ready().
• ready() tells the parent (or your process manager) that the service is ready.
• systemd_tcp_listener(port) uses socket activation if available.

Structs
