Log Message:
Fix 5 bugs: data races, double-start, auth disconnect, cnd_broadcast (items 58-73)

- Move channel flag pre-checks (open/eof_sent/close_received) into
  dssh_conn_send_data() and dssh_conn_send_extended_data() under buf_mtx,
  fixing data races in write paths (items 58, 59)
- Change dssh_session_start() double-start guard from demux_running to
  conn_initialized; clear flag in dssh_session_stop() (item 68)
- Add DSSH_AUTH_DISCONNECT callback return value so server auth callbacks
  can reject and disconnect clients (item 70)
- Replace all cnd_signal(poll_cnd) with cnd_broadcast to wake all waiters
  when multiple threads poll the same channel (item 73)
