Brian Harrison de02f9cccf Handle cold-boot timeout for TCP connections ...

- bridges/tcp_serial_bridge.py: increase default boot_delay 2s → 8s to
  cover MiniMate Plus cold-start time (unit wakes from RS-232 line
  assertion but takes 5-10s to be ready for POLL_PROBE).
- sfm/server.py: add _run_with_retry() — on TCP connections only, retries
  once on ProtocolError. Serial timeouts are not retried (usually a real
  fault). Confirmed behaviour: unit wakes purely from RS-232 line voltage,
  no software wake-up frame needed.
