drift_flutter pulled sqlite3_flutter_libs, whose bundled plain SQLite exports
the same sqlite3_* symbols as sqlcipher_flutter_libs. With both loaded the app
segfaulted at startup on Linux desktop when opening the encrypted DB (the app
built and the Dart VM started, then crashed natively — "Lost connection").
drift_flutter was unused (we open the DB via our own encrypted executor), so
removing it drops sqlite3_flutter_libs and leaves SQLCipher as the only native
sqlite provider. 37 tests green; Linux build runs without crashing.
