Subject: [PATCH 1/2] fix(preview): unpack all three values returned by
 _auto_compile_prompts

_auto_compile_prompts() returns a 3-tuple:
  (compiled_command, compiled_prompt_files, runtime_content)

The preview() command was unpacking only 2 values in both its rich-UI
path and its fallback except (ImportError, NameError) path, causing
apm preview to always crash with:

  ValueError: too many values to unpack (expected 2)

Fix: add _ to capture the unused runtime_content in both call-sites.
_execute_script_command already unpacks all three values correctly.

Fixes: apm preview <script> crashes for any script definition
