Langfuse Prompt Migration

Migrate hardcoded prompts to Langfuse for version control, A/B testing, and deployment-free iteration.

Prerequisites

Verify credentials before starting:

echo $LANGFUSE_PUBLIC_KEY   # pk-...
echo $LANGFUSE_SECRET_KEY   # sk-...
echo $LANGFUSE_HOST         # https://cloud.langfuse.com or self-hosted

If not set, ask user to configure them first.
