`Connection::list_tables` took a `lance_namespace::models::ListTablesRequest` directly, so its generated shape -- including `identity`, `context` and `include_declared`, none of which lancedb reads -- was part of the public API, and Node had no binding at all. Replaces it with a `ListTablesBuilder` carrying `page_token`, `limit` and `namespace`, matching every other operation on `Connection`. This is a breaking change for Rust callers. Node gains `listTables` with `ListTablesOptions` and `ListTablesResponse`; Python's public API is unchanged, since it already had `list_tables` everywhere. `table_names` and `TableNamesBuilder` are deprecated. Its `start_after` takes a table name rather than an opaque token, which cannot be pushed down into a store that resumes from a continuation token. Also fixes the page boundary in `ListingDatabase::list_tables`: the token was the first name of the next page while resuming skips names at or before the token, so one table was dropped per boundary. Walking `[a, b, c, d, e]` with a limit of 2 returned `[a, b, d, e]`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Usage
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);
