obsidian-sorter: automated note filing for an Obsidian vault

Classifies notes from an inbox folder and files them, with a human
approval step. Zero third-party dependencies.

- type mirrors folder (200 projects / 300 areas / 400 Personal Family)
- TypeSafe JEV for semantic classification (~$0.0001 per note)
- watcher writes a proposal INTO the note; the owner ticks a checkbox
- systemd user service on .27, 10s poll
- 15/15 functional tests
