Update nightwatch75/todo to 0.0.9 — drag-and-drop reorder (plugin API 5) (#91)

Manual-mode reordering now uses declarative drag-and-drop (ui.dragSource
/ ui.dropZone, plugin_api 5) instead of the two-click grip; also folds in
the 0.0.8 crash-loop fix (strike() gated on utf8.len) and an onExit
autosave flush. Translation keys nested for the validator.

 ### Reordering in manual mode
 
-The noctalia plugin UI exposes no drag callbacks (only clicks), so the ☰ grip
-reorders with two clicks instead of a drag:
-
-1. Click a row's ☰ grip — it lights up; that row is now "held".
-2. Click another row's ☰ grip — the held row drops in just above it.
-3. Click the held row's own grip again to cancel.
+Grab a row by its ☰ grip and drag it. Thin insertion zones open up between the
+rows as you drag; drop the row on one to move it there. This uses noctalia's
+declarative drag-and-drop, which needs plugin API ≥ 5.
