/**
 * agentCoreBrowser — AWS Bedrock AgentCore **Browser** as a {@link BrowserRunner}.
 *
 * A managed Chrome in AWS's account that an agent can drive, a person can watch
 * live, and — the part this adapter exists for — a person can TAKE OVER
 * mid-session and hand back.
 *
 * ── Two channels, and only one of them is here ───────────────────────────────
 * A browser session has two doors, and confusing them wastes a day:
 *
 *   1. **The automation stream** — a CDP WebSocket. Navigate, find an element,
 *      fill a form: everything page-shaped happens here, driven by Playwright
 *      or another CDP client. This adapter hands you
 *      {@link BrowserSession.automationEndpoint} and stays out of the way. It
 *      does not depend on Playwright and does not drive the page for you.
 *   2. **`InvokeBrowser`** — the data-plane operation this adapter calls. It is
 *      OS-LEVEL input ABOVE the page: mouse, keyboard, screenshots. Its action
 *      union, read off the SDK rather than remembered, is exactly
 *      `mouseClick | mouseMove | mouseDrag | mouseScroll | keyType | keyPress |
 *      keyShortcut | screenshot`. **There is no navigate action**, and a reader
 *      expecting one is looking at the wrong door.
 *
 * ── The takeover ─────────────────────────────────────────────────────────────
 * `UpdateBrowserStream` with `automationStreamUpdate.streamStatus` set to
 * `DISABLED` stops the automation channel and leaves the live-view user in
 * control; `ENABLED` gives it back. That is `handControlTo('person' | 'agent')`
 * here, and it composes with this library's check-in: the agent pauses, a
 * person finishes the login, the agent resumes on the page they left — and both
 * handovers are ordinary events in the trace.
 *
 * ── How this talks to the SDK (the 9.4.0 law) ────────────────────────────────
 * Through `client.send(new SomeCommand(input))`, never a method on the client —
 * a bare `@aws-sdk/client-*` Client carries `send` and `destroy` and nothing
 * else. Every command name and request shape below was read off a real install
 * of `@aws-sdk/client-bedrock-agentcore` **3.1118.0**, including the action
 * union above and `ScreenshotResult`'s `{ status, error?, data? }`.
 *
 * ── One documented contradiction, left as AWS wrote it ───────────────────────
 * The devguide says a session defaults to 15 minutes; `StartBrowserSession`'s
 * API reference says 3600 seconds. This adapter sends nothing unless you pass
 * `sessionTimeoutSeconds`, so the default is whatever the service applies —
 * rather than this file picking a side in somebody else's disagreement.
 *
 * Pattern: Adapter (GoF) + lazy peer-dep load — the SDK is required only when
 * `start()` first runs, or never, if you inject `_client` / `_sdk`.
