tutorial() opens an empty window

[DasOhmoff]

Hey, I think tutorial() has conflicting prompt instructions right now.

Steps to reproduce

1. Use 99 and trigger tutorial()
2. Give it a normal prompt that should produce a Markdown tutorial
3. The request completes, but the tutorial window is empty

Expected behavior

tutorial() should write a Markdown tutorial to TEMP_FILE, and the opened tutorial window should show that content.

Actual behavior

Sometimes TEMP_FILE ends up empty, and tutorial() still opens a blank window.

Cause

tutorial() asks for a tutorial in Markdown, but 99 also reuses the generic temp-file rule that says things like:

• Return only the code.
• ONLY provide requested changes by writing the change to TEMP_FILE
  

  99/lua/99/prompt-settings.lua

  Line 114 in ec9872f

  never provide the requested changes as conversational output. Return only the code.

That seems fine for visual/search-style code edits, but not for tutorials. A tutorial is not code, so the instructions conflict.

What fixed it for me

I patched my local config so that tutorial() uses a tutorial-specific temp-file rule instead, f.e.:

NEVER alter any file other than TEMP_FILE.
never provide the tutorial as conversational output.
ONLY provide the tutorial by writing valid Markdown to TEMP_FILE.

After that, tutorial() stopped opening empty windows on my machine.

Suggested fix

Use a tutorial-specific temp-file rule instead of the shared code-edit rule.

Thanks for this nice plugin.
