feat: referentiel projets dynamique + validation nommage by design

Durcit la convention de nommage des projets (dérive constatée : 'Sliding
Automation', 'code_versioning'... au lieu des formes canoniques).

- trilium_api.py : projets_canoniques() lit le référentiel = valeurs du label
  projet sur les notes de type=projet (source unique, pas de constante en dur).
  Note-projet CodeVersioning créée (manquait).
- mcp_server.py : _valider_projet() branché dans les 6 tools de création
  (add_decision/history/backlog, new_conversation, create_entite, add_skill).
  Refuse un projet non canonique (suggestion si faute) ou inconnu (renvoi au
  processus de création de projet). Ne verrouille pas si référentiel illisible.
- lint_audit.py : VAL-nommage aligné sur le référentiel (attrape casse, espace
  ET snake_case ; l'ancien 'contient un espace' ratait code_versioning).
- Données : 79 notes ré-étiquetées vers les 3 formes canoniques.

Quality by design : l'erreur de nommage devient impossible à l'écriture, le
Lint n'est plus que le filet de sécurité.
