bsi-db.py — Wrapper SQLite léger pour les scripts BSI bash.
Remplace sqlite3 CLI (pas toujours installé).

Usage :
  python3 scripts/bsi-db.py "SELECT * FROM claims"           → query, pipe-separated
  python3 scripts/bsi-db.py -exec "INSERT INTO ..."           → write (no output)
  python3 scripts/bsi-db.py -script "CREATE TABLE ...; ..."   → multi-statement
