feat(todo,meditate): what a setting does behind its question mark

The developer's review of 3 Nov 2026 (ADR 0033, D25): an explanation stands
one tap away, behind halkyon_ui's HelpButton beside the setting's name,
rather than always below it. Todo: resetting sub-tasks, the automatic
reminder (its value stays below), counting a recurrence from completion.
Meditate: keeping the screen on, the streak, the morning's dream prompt.
What is the person's own (a value, a count) stays in view; an empty list's
message and quick add's hint about highlighted words, shown only while
there are some, stay too.
