Allow assistant to access output from commands executed with ! prefix

### Describe the bug

Problem

Currently, when I execute commands directly using the ! prefix (e.g., !ping google.com), the
assistant cannot see the output of those commands. This creates a disconnect where I can run
commands myself, but then cannot ask the assistant to analyze or interpret the results.

Current Behavior

- User runs: !ping google.com
- Command executes and shows output in terminal
- User asks: "what are the results of the ping command to google.com?"
- Assistant responds: "I don't have access to commands you run directly with !"

Expected Behavior

When a user runs a command with !, the output should be accessible to the assistant in
subsequent interactions within the same session, allowing the assistant to:

- Analyze command results
- Answer questions about the output
- Provide insights based on the data

Use Case

This would enable a more natural workflow where users can:

- Quickly execute commands themselves using !
- Ask the assistant to interpret, summarize, or analyze the results
- Get help troubleshooting based on actual command output
