Problem

The current terminal command parsing for the send to terminal button assumes the command is on the first line. Some suggested terminal commands span multiple lines and are more complex.

Also sometimes there are multiple terminal commands in a single response.

Solution

Improve the parsing logic to find the entire terminal command.

Improve the system message to always split the suggested commands into separate blocks if possible.
