Three faults in one path, all made reachable by the watchdog.
A callback returning just past the timeout ran against state that no longer belonged to it. It nil'd chime--process, which by then held the replacement child, so the overlap guard broke and a third child could spawn. It also reset the failure counter the watchdog had just incremented. Each spawn now captures a generation, and a result whose generation is stale is discarded whole.
interrupt-process only asks. A child stuck in a blocking read ignores SIGINT and lives on as a zombie, invisible because chime--process was already cleared. The watchdog and chime--stop now call chime--kill-async-process, which silences the sentinel and calls delete-process.
async.el kills a child's process buffer only on a zero exit, so every signalled child leaked one. With a persistent hang that's a buffer per chime-async-timeout until Emacs restarts. The kill path reaps the buffer itself.
chime--stop also clears chime--consecutive-async-failures and chime--process-start-time, so a later chime-mode doesn't resume with the old count.
