fix: /local-workspace — chemin du header + clic sur un dossier du sidebar (v7.69.9)

Corrige deux régressions de /local-workspace :

- le chemin du header restait bloqué sur « Home / <workspace> » quel que
  soit le dossier affiché : la route rend désormais breadcrumb_items
  (Home / <workspace> / <dossier> / <sous-dossier>, niveaux cliquables,
  collapse « … » au-delà de 4) et la navigation sans rechargement recalcule
  le chemin via l'event flowdeck:breadcrumb-changed ;
- le clic sur un dossier du sidebar affichait TOUS les composants à la
  fois : Alpine.data('wsInitData') retournait le même objet singleton, le
  2e montage (navigation partielle) levait « Cannot redefine property:
  \ » et initTree abandonnait, laissant tout le contenu au state
  brut. La factory retourne désormais une enveloppe fraîche par montage
  qui délègue à l'état réactif partagé. #lw-config est aussi relu à chaque
  exécution (le 2e montage gardait le folder_id du 1er chargement).

Inclus également le travail en cours de l'arbre : Library (colonnes Last
visited/Source, ordre d'en-tête, favoris à icônes Workspace), Meeting
Notes (bloc, CSS, routes, docs), coloration de code hljs, badges
favori/publié dans l'arbre local-workspace, docs (DATA_MODEL,
architectures) et tests associés.
