timeline_ribbon

Horizontal lifecycle ribbon for a requirement ( or focused entity ), not a single " last modified " label.
Show milestones along a line toward Now — e. g. created, first implementation,
last reviewed, current edit, last test — so maturity and recent activity
are visible in one glance.
Consumes requirement_lifecycle_signals and temporal_signals.
Fits scope_pane_design. focus_hero and requirement_card.
