chore(deps): go mod tidy — promote fsnotify to direct

No functional change. Groups yaml.v3 and fsnotify as direct deps,
isolates golang.org/x/sys as indirect.

-## [0.4.0] - 2026-04-16
-**Type:** Minor — Phase 2 / Chantier G2 : dispatcher enforce depends_on
+## [0.3.9] - 2026-04-16
+**Type:** Patch — `go mod tidy` (fsnotify direct dep cleanup)
 
-### Ajouté
-- `internal/dispatcher/dispatcher.go` : champ `DependsOn []string` ajouté à
-  `TaskFrontmatter` et nouvelles méthodes `taskBlocked`, `dependencyResolved`,
-  `touchBlockedMarker`, `isSafeSegment`.
-- Avant de claim une session pour une tâche, le dispatcher parse le
-  frontmatter. Si `depends_on: [project:task_id]` est non vide ET non résolu
-  (sibling task pas encore dans `<projectsDir>/<project>/.agent-queue/done/`),
-  la tâche est sautée et un fichier `<task>.md.blocked` est posé à côté.
-- Le marker `.blocked` est idempotent : sa mtime n'est PAS rafraîchie aux
-  passes suivantes pour que le watchdog (G1) puisse compter le timeout
-  depuis la première détection.
-- Sécurité : segments `project` / `task_id` validés (`[A-Za-z0-9._-]+`,
-  refus de `..`, `/`, NUL) avant d'être concaténés au filesystem path.
-- `assignNextTask` (chemin du session done-channel) applique la même règle.
+### Modifié
+- `go.mod` : `fsnotify` promu en dépendance directe, `yaml.v3` regroupé, `golang.org/x/sys` isolé en indirect. Aucun changement fonctionnel.
 
-### Tests
-- `TestDispatcher_DependsOnUnresolved_DropsBlockedMarker`
-- `TestDispatcher_DependsOnResolved_Dispatches`
-- `TestDispatcher_DependsOn_PartialResolution`
-- `TestDispatcher_DependsOn_RejectPathTraversal`
-- `TestDispatcher_BlockedMarker_Idempotent`
-- `TestDispatcher_NoDependsOn_DispatchesNormally` (regression guard)
-- `-race` clean.
+### Tests effectués
+- ✅ Build OK (aucune modification de code)
