feat: split drift recipes and add 'just undeclared'

- 'just status' now a thin wrapper for 'pkg-drift + dotfile-drift'
- 'just pkg-drift' and 'just dotfile-drift' are individually addressable
- 'just undeclared' prints undeclared packages unindented, one per line,
  so they pipe cleanly into 'paru -Rs -'
- pkg-drift reuses 'just undeclared' via sed to avoid duplicating logic
