feat: menu contextuel de bloc refondu façon Notion — 10 actions, sous-menus et raccourcis (v7.61.0)

- panneau de gauche : recherche « Search actions... », section « Text », les
  10 actions dans l'ordre Notion (Turn into, Color, Copy link Alt+⇧+L,
  Duplicate Ctrl+D, Move to Ctrl+⇧+P, Delete Del, Comment Ctrl+⇧+M,
  Suggest edits Ctrl+⇧+Alt+X, Ask AI Ctrl+J, Skills) + pied métadonnées
  (auteur / heure de dernière édition / mots-caractères du bloc)
- panneau de droite au survol (fermeture différée) : Turn into avec ✓ du
  type actuel + Heading 1-4, listes, To-do, Toggle, Code, Quote, Callout,
  Block equation, Synced block, 2/3/4/5 columns (info-bulle « Create N
  columns of blocks ») ; Color avec Last used / Text color / Background
  color (10 couleurs nommées, ✓ courante, carré de couleur) ; Skills =
  compétences réelles de l'espace appliquées au bloc via l'IA
- turnInto(idx,type,cols) : crée N colonnes, sélecteur de source pour les
  blocs synchronisés ; setBlockColor mémorise la dernière couleur (Ctrl+⇧+H)
- nouvelles actions éditeur : commentBlock (sélection + tiroir), askAI
  (composeur sans effacer le bloc), suggestEdit / runSkill (IA, insertion
  sous le bloc), applyLastColor
- raccourcis : handler clavier dédié (Ctrl+J, Ctrl+⇧+H, Ctrl+⇧+M,
  Ctrl+⇧+Alt+X, Alt+⇧+L, Ctrl+⇧+P, Ctrl+D sans double, Del seulement avec le
  menu ouvert, Échap) — les entrées Copy/Cut/Paste du menu sont retirées
  (Ctrl+C/X/V conservés)
- styles : .bm-group, .bm-foot, .bm-check, .bm-current, .bm-dot, sous-menu
  60vh, recherche focalisée à l'ouverture
- tests : tests/test_v761_block_menu.py (9 tests, dont node : colonnes) +
  test_v7593 adapté ; suite complète 1362 passed / 0 failed, ruff 0, eslint 0
- livraison : VERSION + app/main = 7.61.0, OpenAPI 525 chemins, CHANGELOG
