drey 0.1.9

Fixed

• The daemon's socket, lock and log lived under dirs::cache_dir()
  (~/Library/Caches/drey on macOS) when neither DREY_RUNTIME_DIR nor
  XDG_RUNTIME_DIR was set. That directory is fair game for the OS and for
  cache-cleaning tools to prune at any time, including while the daemon is
  still running: once daemon.sock is gone, the daemon keeps listening on a
  path nothing can reach, and the next client, finding no socket there,
  starts a second daemon rather than reusing the first. Repeated over days
  this produced a pile of idle, unreachable drey daemon processes that
  never exited on their own. The fallback now prefers the system temp
  directory ($TMPDIR on macOS) over the cache directory, and the daemon
  also checks every 60 seconds that its socket path still points at its own
  listener, exiting if it doesn't, so an orphaned daemon cleans itself up
  instead of accumulating indefinitely.
