fix: add fallback to local find/grep for failed remote live actions

When remote 'live_find' or 'live_grep' actions fail (e.g., connection not found, or the live action itself fails), the system now gracefully falls back to performing a local 'find' or 'grep' operation.
This enhances robustness and user experience by ensuring that a search or find operation is always attempted, even if the remote live action encounters an issue.
