CollinRobison/markdown-journal-cli ? reverse-engineered prompt

Build me a command line tool for keeping a markdown journal organized.

I want to be able to create a new journal, turn an existing folder of notes into a managed journal, add new entries, and run an update command that keeps everything in sync. It should track file changes, generate a table of contents automatically, and update journal metadata safely so it does not mess up files if something changes halfway through.

The journal should use normal markdown files, plus a small config file and hidden metadata files for tracking and TOC data. It should also support ignoring some files from the table of contents while still tracking them, and fully excluding other files from tracking. Make the commands feel simple and friendly, with good help text and clear output. If you need to check current .NET docs or CLI patterns while building it, go ahead and look them up online.
