/todos: a kanban board over the todo/ tree, owner-only

The filesystem is the database: GET reads the tree through the same module the
index generator now imports, PATCH splices frontmatter (status, priority, due,
order) and never touches a body byte, and every write regenerates TODO.md.
Columns open/doing/blocked/done, native drag between them, selection and theme
filter in the URL. Registry entry 'todos' (kind admin, 22 entries, docs:check
green), isSuperAdmin double-gate on the router.
