New PKM tool for MacOS

PuzzlePKM is a new macOS-native PKM app with a local-first design and a CLI-friendly workflow.

It offers both a desktop UI and command-line access, with rich linked notes and backlinks.

Data is stored locally in SQLite and synced to user-controlled folders for portability and backups.

The app gives Mac users an offline, backup-friendly knowledge management option with full local control.
