Extra guide text output in no-interactive mode

[yoskoh]

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

macOS 15.4.1 (24E263)

Expected behaviour

In no-interactive mode, only the response from Amazon Q should be output, without any additional UI guide text.

Actual behaviour

From v1.8.0, two lines of guide text are being output to stdout in no-interactive mode:

/help all commands  •  ctrl + j new lines  •  ctrl + k fuzzy search

This is problematic for automated tools that parse Q's output.

Steps to reproduce

Run a command like:

echo "This is sample document."|(PROMPT='Say only the answer against the question simpliy,with no comment, no quart. Answer following document in Japanese.';echo "$PROMPT";echo "---";cat -)|q chat --no-interactive

The output includes the guide text before the actual response:

/help all commands  •  ctrl + j new lines  •  ctrl + k fuzzy search
