feat(backend,domain,infrastructure,application,app-tauri,web-server,frontend): suppression d'un projet du registre IdeA sans toucher son dossier disque — #308 (QA verte)

cause: l'utilisateur ne pouvait pas retirer un projet du registre IdeA (projects.json) ; la seule issue laissait l'entrée fantôme dans la liste des projets, sans capacité générique de retrait.

domain: port ProjectStore::remove_project(id) -> Option<Project> avec implémentation par défaut « not supported » pour ne pas casser les stores spécialisés.

infrastructure: FsProjectStore implémente remove_project — retire l'entrée du registre persisté et la renvoie, None si id inconnu, ordre relatif du registre préservé ; test store dédié.

application: use case RemoveProjectFromRegistry (remove.rs) — NotFound explicite si id absent, retourne le projet retiré + registre rafraîchi.

backend/app-tauri/web-server: DTO RemoveProjectRequestDto/RemoveProjectResponseDto (removed, projects, restore_state, was_open), adapter partagé remove_project_for_adapter réutilisé par la commande Tauri remove_project et la route HTTP — même contrat desktop/web ; remove_project_and_deactivate désactive le projet s'il était ouvert, purge l'entrée open-projects restore correspondante et renvoie was_open/restore_state ; test adapter vérifiant le contrat de bout en bout (entrée retirée, restore purgé, root intact).

frontend: DTO + ProjectGateway.removeProject (HTTP + mock), ProjectsView expose un menu d'actions projet (ProjectActionsMenu) avec entrée Retirer, RemoveProjectDialog — confirmation explicite précisant que le dossier disque n'est pas supprimé, invalidation/rechargement de la liste des projets après succès (useProjects), tests ProjectsView/projects/adapters/httpInvoker/services.

QA verte: cargo targeted tests/check OK (domain, application project_usecases, infrastructure project_store, backend, app-tauri, web-server), npm targeted/typecheck/build OK ; suite npm test complète rouge non bloquante hors #308 (échecs préexistants listProjectSettings/web). Vérifications Git: git diff --check OK, cargo fmt --all -- --check OK.

fichiers .ideai/tickets/308/, tickets/counter.json, tickets/index.json, attachments/ et scripts/ hors périmètre et préservés en worktree (sync store traité séparément) ; aucun push.
