Dangers of vibe coding, best to avoid!

This prompted me to improve our debugging situation. So, I implemented
detailed tracing.
https://klaus.systemreboot.net/kaagum/commit/7918c9d422962d8dec4fb9fa410a51daa6d6ebe7/

Now, if you run kaagum with the "--trace-file=/path/to/some/file"
option, we should be able to see what's going on.

If you are on Emacs agent shell too, here's my setup:

(setq agent-shell-kaagum-command
      ;; replace with path to your kaagum
      "/gnu/store/lvxz7hdcwydhv7w8rnnhczl0xl6jlh7q-kaagum-0.1.0/bin/kaagum"
      agent-shell-kaagum-parameters
      '("--api-key-command=pass dev/openrouter.ai | awk '/^API Key:/ {print \$3}'"
        "--model=anthropic/claude-sonnet-4.6"
        "--trace-file=/tmp/logs"))

Regards,
Arun
