`cargo deny` did not check crate-level dependency declarations against `[workspace.dependencies]`, so a crate used by both the core crate and the bindings could be declared independently in each one and drift. For example `tokio` was pinned at `1.23` in `rust/lancedb` and `1.40` in `python`, and `pin-project` at `1.0.7` in the workspace table but `1.1.5` in `python`. This PR turns on cargo-deny's `bans.workspace-dependencies` lint, which fails when a dependency is used by more than one member without going through `workspace = true`, and when a `[workspace.dependencies]` entry is used by nobody. Enabling it surfaced 12 violations. Fixing them means adding `bytes`, `lancedb`, `serde`, `serde_json`, `tempfile`, `tokio`, and `uuid` to `[workspace.dependencies]`, and pointing the `arrow`, `arrow-buffer`, `async-trait`, `chrono`, and `pin-project` declarations at the entries that already existed. `Cargo.lock` is unchanged, so resolution is the same as before. The shared `chrono` entry now carries `default-features = false, features = ["clock"]`, matching what `nodejs` and `python` already asked for — cargo ignores a member's `default-features = false` unless the workspace entry sets it too. On the targets we build, `clock` covers everything `rust/lancedb` was getting from chrono's defaults. 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);
