chore(release): Kanbante 0.19.0 — performance et pilotage (A + C)

- /forecast : une ligne par jalon, tous projets, triée par
  risque (écart décroissant), filtrable, ancres ms-<owner>-<repo>
  pointées par le bloc jalon des cartes du dashboard ; débit
  par projet conservé en tableau compact.
- /health : tableau trié par sévérité (pastille, zombies,
  goulot) ; page détail : sélecteur de projet (health.js).
- Tri des tableaux mutualisé dans static/js/tablesort.js
  (dashboard, forecast, health).

 # Changelog
 
+## 0.19.0 — 2026-10-12
+
+### Performance + navigation « Pilotage » (chantiers A + C, décidés par Bruno)
+
+- **Parallélisation (A1)** : les pages inter-projets (dashboard,
+  /health, /forecast, /triage, /wall) attendaient chaque dépôt à
+  la queue leu leu ; elles utilisent maintenant un `asyncio.gather`
+  borné (16) — le patron que /focus appliquait déjà.
+- **Cache stale-while-revalidate (A2)** : les listes Gitea
+  (dépôts, issues, jalons, étoiles) sont servies immédiatement
+  même périmées, et rafraîchies en tâche de fond. Fini le
+  « mur » de rechargement à chaque expiration du cache (30 s) :
+  seul le tout premier chargement après un démarrage paie le
+  coût complet. Les mutations vident le cache et désarment les
+  rafraîchissements en vol (aucune donnée périmée ressuscitée).
+- **Prévisions refondues (C1)** : /forecast devient un tableau de
+  bord des jalons **tous projets** — une ligne par jalon (projet,
+  échéance, progression, ETA, **écart**, débit), triée par risque,
+  filtrable, colonnes triables ; le bloc jalon des cartes du
+  dashboard y pointe directement (ancres). Le débit par projet
+  reste en dessous, en tableau compact.
+- **Santé refondue (C2)** : /health devient un tableau trié par
+  sévérité (pastille, ouvertes, zombies, goulot) ; la page santé
+  d'un projet gagne un **sélecteur de projet** pour basculer sans
+  repasser par l'index. Le tri des tableaux est mutualisé
+  (`static/js/tablesort.js`, dashboard inclus).
+- Mesuré sur l'instance réelle (depuis le réseau de test) :
+  pages chaudes 0,04–0,16 s ; le premier chargement à froid
+  reste de quelques secondes — le chantier B (instantanés
+  d'arrière-plan) demeure le levier pour le supprimer, si voulu.
+
