chore(release): v1.14.0 — animated health scores, score explanations, mood-factor correlations, log past doses

- The health-score strip is rebuilt as a calm, staggered signature reveal with
  a distinct colour per score, a soft glow, and a "vs your normal" reference
  arc — once per visit, reduced-motion-safe.
- Each Readiness / Sleep / Recovery / Strain / Stress score sheet carries a
  short plain-language explanation of why the score landed where it did
  (additive `assessment` field on the derived endpoint; fills without a
  provider).
- Rated mood factors (work / sleep quality / stress …) are correlated against
  vitals as a new card the assistant can cite — confidence-gated, observational.
- Medications "Add" splits into log-intake (incl. backdated) vs new medication;
  sparse weekly/rolling meds show an open-cycle status line instead of a bare
  percentage.
- Insights polish: equal-height trend cards, briefing heading above the card,
  coach tone + length side by side.
