Fix SQL driver TCK tests: use sqlite3 instead of better-sqlite3

[Copilot]

The SQL driver TCK test suite was failing with "Cannot find module 'better-sqlite3'" because it referenced an uninstalled dependency. All other SQL driver tests use sqlite3 (already in devDependencies), but tck.test.ts was an outlier.

Changes

• Database client: Changed from better-sqlite3 to sqlite3 for consistency with other test files
• Table initialization: Added driver.init() call in beforeEach hook to create the tck_test table that TCK tests expect
• Connection cleanup: Added driver['knex'].destroy() in afterEach to prevent connection leaks

Impact

Before: 34/34 TCK tests failed (module not found)
After: 26/34 TCK tests pass

The remaining 8 failures are pre-existing driver implementation gaps (findOne returns undefined vs null, bulk operation metadata, etc.) unrelated to this fix.

    () => {
        driver = new SqlDriver({
-           client: 'better-sqlite3',
+           client: 'sqlite3',
            connection: { filename: ':memory:' },
            useNullAsDefault: true
        });
        return driver;
    },
    {
        hooks: {
            beforeEach: async () => {
+               await driver.init([{ name: 'tck_test', fields: {...} }]);
            },
            afterEach: async () => {
+               if (driver?.['knex']) await driver['knex'].destroy();
            }
        }
    }
);

Pull request overview

This PR fixes the SQL driver TCK test suite which was completely failing due to a missing dependency reference. The fix changes the SQLite client from better-sqlite3 (not installed) to sqlite3 (already in devDependencies), adds proper table initialization via driver.init(), and ensures clean connection teardown.

Changes:

• Changed SQLite client from better-sqlite3 to sqlite3 for consistency with other test files and available dependencies
• Replaced manual table-dropping logic with driver.init() call to create the tck_test table with proper schema
• Added connection cleanup in afterEach to prevent resource leaks
