13 bite-sized tasks with TDD on the Rust side (migrations +
cascade flag + list_recent_completions query + 4 storage tests) and
incremental frontend wiring (store, sparkline component, Tasks header
badge, event dispatches, settings toggle). Verification pass + roadmap
and HANDOVER update as final tasks.

Covers today's completion count badge + 7-day momentum sparkline on the
Tasks header. Chose to exclude auto-cascade parents from the count via a
new auto_completed column (migration v13), to respect the zero-loss
framing. Sparkline is a new settings toggle, default on.
