chengyongru e2955a2e12 fix(weixin): prevent silent message drops from poll exceptions and expired tokens
- Remove suppress(Exception) from poll loop and message processing; add
  logger.exception so inbound errors are visible.
- Check both ret and errcode on send to avoid silent drops when iLink
  returns ret != 0 with errcode == 0.
- Proactively refresh context_token via getconfig before sending if the
  cached token is older than 60s. This prevents message loss on long
  agent turns and cron pushes without relying on complex retry logic.
