Summary

Implements the five history / mid-cycle analytics surfaces:

1. Sprint pulse (/sprint-pulse) — date-window coaching view with achievement / Jira / Bitbucket throughput, themes, concerns, and evidence freshness (stale-only cites)
2. Person timeline — chronological dossier + reviews + concerns + rating decisions on each person page
3. Rating trends — cross-cycle overall / competency team averages with sparklines on Team performance
4. Cycle compare — distribution shift, movers (±1+), repeat thin dossiers, theme drift
5. Evidence freshness — folded into sprint pulse (in-window vs older evidence + draft cite staleness)
