Fall back to 'SQLite' when /version endpoint is unavailable

[IceboxDev]

Turso's managed libSQL service does not expose a /version endpoint at all:

curl -H "Authorization: Bearer $TOKEN" https://<turso-host>/version
# HTTP/1.1 404 Not Found
# {"error":"route not found: [\"version\"]"}

LibSqlDatabaseMetaData.readServerVersion propagates the resulting IOException as SQLException, so getDatabaseProductName() throws. Clients that rely on the product name to pick a SQL dialect (JetBrains DataGrip / PyCharm in particular) classify the connection as UNKNOWN, which downstream causes a hang on result-set finalization.

Fix: when /version is unreachable, fall back to a static "SQLite" product name. libSQL is SQLite-compatible at the SQL level, so this gives clients a sensible dialect to pick. If /version is reachable (self-hosted product name. libSQL is SQLite-compatible at the SQL level, so this gives clients a sensible dialect to pick. If /version is reachable (self-hosted sqld), the actual server version is used as before.
