Pull request overview

This PR refines the Private Notes voice flow by adding topic search, reducing prompt exposure of note bodies by default, and centralizing destructive-action confirmations in Python for consistent safety behavior.

Changes:

• Added search_notes tool and updated the voice loop contract to support topic/keyword queries.
• Adjusted tool loop parsing/handling to be more resilient and to prevent confirmations via ask_followup.
• Hardened persistence behavior by validating stored notebook shape and refusing to operate on malformed storage.
