Fix code review issues: replace label, observed names for disconnect/remove

- Fix ContainerReplaceLabel detection: use op.Inherited != nil (not
  op.Container) as signal for recreate in execCreateContainer
- Use observed network name (not desired) for DisconnectNetwork and
  RemoveNetwork operations, in case the name changed
- Use observed volume name (not desired) for RemoveVolume operations
- Update reconciliation.md with 3 new lessons learned (7.8, 7.9, 7.10)

+### 7.8 Disconnect/Remove utilisent les noms observes, pas desires
+
+Quand un reseau ou volume a diverge, les operations de disconnect et remove doivent
+cibler la ressource **observee** (l'ancienne), pas la ressource **desiree** (la nouvelle
+config). Si le nom a change entre les deux, utiliser le nom desire pour le remove
+echouerait ou supprimerait la mauvaise ressource. Seul le `CreateNetwork`/`CreateVolume`
+utilise le nom desire.
+
+### 7.9 Le label ContainerReplaceLabel necessite un signal fiable pour le recreate
+
+Dans `execCreateContainer`, le label `api.ContainerReplaceLabel` doit etre ajoute pour
+les conteneurs crees en remplacement d'un autre (recreate). Le signal fiable est
+`op.Inherited != nil` (conteneur dont on herite les volumes anonymes), pas
+`op.Container != nil` (qui n'est pas set sur le noeud CreateContainer du recreate).
+
+### 7.10 La boucle `for range` en Go 1.22+
+
+Depuis Go 1.22, les variables de boucle `for _, x := range` sont copiees a chaque
+iteration. Le pattern `x := x` dans les goroutines n'est plus necessaire. Docker Compose
+utilise Go 1.25+. Si le projet devait un jour revenir a une version anterieure a 1.22,
+les closures dans `executePlan` devraient capturer explicitement la variable de boucle.
