Val-sss a809367b86 feat: persistent SSH session via paramiko ...

- Add kaiwu/tools/ssh_session.py: SSHSession class with connect/exec/upload/download/close
- Integrate into ToolExecutor: ssh_connect/ssh_exec/ssh_upload/ssh_download/ssh_close
- Guardrails apply to remote commands too (rm -rf blocked on SSH)
- Persistent connection: connect once, exec multiple commands without reconnecting
- Supports password auth and SSH key auth

Usage flow:
  executor.ssh_connect("183.222.230.89", port=22102, username="linux", password="xxx")
  executor.ssh_exec("systemctl status nginx")
  executor.ssh_exec("cd /app && cat config.yml")
  executor.ssh_close()

311 tests passing.
