v0.7.3 — Finalized BuiltInAgent Fallback Behavior (Non-Invasive)

What's Changed

✅ Changed

• The fallback BuiltInAgent now runs entirely in-memory
• It no longer creates any prompt folders or files on disk

🔒 Design Note

This ensures the toolkit behaves non-invasively by default:

• First-run usage (rschat "question") is fully supported without any setup
• No side effects or file creation occurs unless the user explicitly initiates agent generation

📌 Summary

• Safe for testing, CI pipelines, or ephemeral CLI calls
• Consistent with the project's principle of "facilitate without intrusion"
