What

Match the Python SDK's queue-init defaults in the Node SDK.

• SQLite default — new Queue() now opens .taskito/taskito.db (was: required dbPath/dsn). Missing parent dirs are created automatically, like Python's os.makedirs. :memory: skipped.
• Postgres/Redis — require an explicit dsn, else throw. schema (Postgres, default "taskito") and prefix (Redis) pass through unchanged for per-backend namespacing; both user-overridable.
• Constructor arg now optional (new Queue()).

Why

Parity with Python (db_path=".taskito/taskito.db", schema="taskito"). Zero-config local start; users override path/schema/prefix later.

Tests

sdks/node/test/core/open.test.ts — default path + dir creation, nested-dir creation, dsn-required for non-sqlite. tsc + biome clean. Pure TS, no native rebuild.
