feat(vscode): statut git détaillé, sessions archivées, lien IDE web, fetch/pull (0.2.0)

Reflète la refonte IDE en supervision légère, sans dupliquer l'éditeur :
- statut git fin dans l'arbre (staged/unstaged/conflits + dernier commit) ;
- commande « Open Worktree IDE » → deep-link /workspace/:repoId/:wt ;
- commandes fetch / pull (ff-only|rebase) sur les worktrees ;
- event WS session_archived + réglage showArchivedSessions (badge + filtre).
README/CHANGELOG + tests (config/rest-client/ws-client).
