🤖 fix: improve bash timeout error message with actual timeout value

[deansheather]

Generated with mux

Improves the bash tool timeout error message to include the actual timeout value that was exceeded, making it clearer for LLMs how to adjust their tool calls.

Before:

Command exceeded timeout

After:

Command exceeded timeout of 3 seconds. You can increase the timeout by setting the `timeout_secs` parameter on the tool call. Do not use the `timeout` bash command to increase the timeout.

The error message now:

• Shows the actual timeout value that was exceeded
• Explains how to increase the timeout via the timeout_secs parameter
• Warns against using the bash timeout command as a workaround

Relates to #652

Good approach. Way better to send the tokens once when the model transgresses vs. on every request.
