feat(view,tests): query blocks stay code in text the agent did not write

Same two misses as the calendar's: the four-frame watch stopped before
Obsidian hid its navbar - a second move of the ground, after the keyboard's
own - and a trigger that arrived while a watch was running was dropped rather
than restarting it. The watch now needs twelve steady frames, restarts on
every trigger, and listens to Obsidian's Capacitor keyboard events too.
