Jack Ye 60577a44cf test(nodejs): cover the accepted and inline view drop through connect()
Exercises `dropViewAsync` against the mock server both ways: a 202 carrying a
`job_id` surfaces that id, and a 200 -- nothing was bound to the name -- yields
an already-finished job with none.

The wire key is written as raw JSON rather than an object literal, which is what
the rest of this file does and what keeps `useNamingConvention` off a snake_case
field the server chooses.

Basic Example

import * as lancedb from "@lancedb/lancedb";
const db = await lancedb.connect("data/sample-lancedb");
const table = await db.createTable("my_table", [
  { id: 1, vector: [0.1, 1.0], item: "foo", price: 10.0 },
  { id: 2, vector: [3.9, 0.5], item: "bar", price: 20.0 },
]);
const results = await table.vectorSearch([0.1, 0.3]).limit(20).toArray();
console.log(results);

The quickstart contains more complete examples.
