bin/cli/sqlite.mjs::loadSqlite() had no fallback beyond better-sqlite3, unlike
the real server's driver cascade (src/lib/db/adapters/driverFactory.ts::tryOpenSync,
which tries bun:sqlite -> better-sqlite3 -> node:sqlite). On machines without a
working better-sqlite3 native binary, every `omniroute doctor` DB check reported
a false FAIL even when the actual server was healthy via its own driver cascade.
openSqliteDatabase() now falls back to tryOpenSync() when better-sqlite3 fails
to import, reusing the same already-tested cascade the real server uses instead
of re-deriving a second one.
