Phase 5h slice 1 — adds dashboardProject struct that groups per-row
signals (TodoRow / IssueRow / EventRow / dated docs / optional repo
updated_at) by item.ID into one rollup per project. IsCurrent(now)
implements the §7 contract: pinned OR open-tasks>0 OR open-issues>0 OR
LastActivity within 14d.
No UI change — slice 2 wires the rollup into buildDashboard and the
Tiles template. activityRel produces tight tile-friendly labels
(now / Nm / Nh / Nd) distinct from relativeTime (used on rows).
Test coverage:
- task counts + overdue + soonest-due NextSignal
- COMPLETED VTODOs skipped but their LastModified feeds activity
- issues fill OpenIssues + LastActivity, task beats issue for NextSignal
- repoActivity map feeds LastActivity
- LastActivity = max across todo/event/doc/repo sources
- IsCurrent four branches + the no-signal false case
- pinned-first then path-sorted output order
- Stale flag passes through staleByItem map
- activityRel label shapes + future-flip
