B3.5: settings.sparklineRangeDays (added schema-only in B2b) now drives
the recentCompletions fetch via a reactive effect; new segmented control
in Settings → Tasks lets the user pick 7 / 28 / 90 days. Default 7.
B3.14: /shutdown "Open loops" header softened to "Still here", body
copy updated to remove pressure ("Just naming them helps — nothing to
do here"), truncation tail drops the count. The whole "Still here"
section is now gated by a fresh-start derived flag — when B3.1 lands
and writes reentryFreshStartUntil, this surface auto-suppresses.
