style: rustfmt the issue #7 regression tests (CI format gate)

- fix(stealth): bind iframe contentWindow proxy methods to the real window
  (--launch "Illegal invocation" on srcdoc-iframe pages)
- fix(tabs): re-pin active target when the pinned page is removed (issue #7)
- feat(cli): coordinate click (click <x> <y> / --coords), tabs/get-text
  aliases, clearer find error (issue #8.4)
- fix(observability): screenshot/network stamp @ <url>; network --clear
  enables capture immediately (issues #8.1/#8.3)
- fix(ab-connect 0.4.2): stale sessionId fails loudly instead of routing to a
  random tab (issue #8.1) — needs a Chrome Web Store republish
- restart notice now flags in-memory context reset (issue #8.2)

 Stealth fork of [agent-browser](https://github.com/vercel-labs/agent-browser) — connects to your real Chrome, shares your login sessions, and is undetectable by anti-bot systems.
 
 For basic usage, commands, and API reference, see the [upstream documentation](https://github.com/vercel-labs/agent-browser).
 
+## Give your AI agent the browser you already live in

+**No fresh Chrome. No re-login. No "are you a robot?" walls.**
+
+agent-browser-stealth points **any** agent — Claude Code, Cursor, Codex, your own scripts — at the **Chrome you're already signed into everything on**. It clicks in *your* window, so you watch it work and grab the wheel the moment it hits a 2FA prompt or captcha. And because it's literally your real browser (over a one-click extension, native messaging — no debug port), sites read it as 100% human: **[CreepJS scores it 0% bot](#anti-detection).**

+**Why not just use…**
+
+- **Playwright / Puppeteer / browser-use?** They boot an *empty* browser — so you redo every login, fight every captcha, and still get flagged as automation. We use the session you already have.

 `0% stealth` on CreepJS is the key number: because the connect path patches **nothing**, there is no override for a lie-detector to catch. (Dashboards that read `navigator.languages` order or IP geolocation may show a soft "navigator"/"location" flag — that tracks *your real Chrome's* language list and network, not an automation tell.)
 
-When using `--launch` mode (standalone browser), a full suite of stealth patches is applied instead, and it still passes the suite above.
+When using `--launch` mode (standalone browser), a full suite of stealth patches is applied instead, and it passes the suite above — with one caveat: CreepJS reports **~20% stealth** because the srcdoc-iframe `contentWindow` patch trips its `hasIframeProxy` probe (the proxy that hides automation is itself a tell). Everything else is clean (`0% headless`, sannysoft/browserscan green, Cloudflare passed). Set **`AGENT_BROWSER_DISABLE_IFRAME_PROXY=1`** to drop that patch for a clean **0% stealth** (trades the niche srcdoc-iframe masking). The **extension-connect path** (your real Chrome) injects zero JS and is unaffected — it's the genuine 0% path.
+
+### Human-like input (behavioural stealth)
+
+Fingerprint stealth isn't the whole story — the strongest anti-bot vendors (Akamai, PerimeterX, DataDome) also score *behaviour*. A click that teleports the cursor to an element's exact centre with no approach path and zero press delay is a tell, **even though our CDP events are `isTrusted`**.
+
+With humanize on, the cursor moves like a hand: clicks follow a curved, decelerating Bézier path and land on a jittered point *inside* the element (never the dead centre); typing uses variable inter-keystroke timing; scrolling eases in segments; drags follow a curve. It's **adaptive** — every navigation is probed for known anti-bot vendors (cookies / scripts / globals) and a guarded page auto-escalates to full human motion, while ordinary sites stay instant (zero overhead).
+
+What the page's own `mousemove` stream sees (this *is* what a behavioural detector analyses):
+
+| | trajectory |
+|---|---|
+| **off** (default) | straight lines · dead-centre · instant |
+| **human** | curved trails · slow-in/slow-out · off-centre landings |
+
+Control with `--humanize off\|fast\|human` or `AGENT_BROWSER_HUMANIZE`. Default `off`; the adaptive detector escalates per page.
+
+### Silent operation
+
+Driving your real Chrome should never interrupt your work. The agent operates **entirely in the background**: new tabs open un-focused (in their own colored per-session tab group), the agent **never force-fronts a tab**, and `Emulation.setFocusEmulationEnabled` keeps each agent tab rendering and reporting `document.hasFocus()` / `visibilityState: 'visible'`. So screenshots still work, pages aren't render-throttled, and "the tab was hidden the whole session" never becomes its own bot tell. You keep working in your active tab; the agent works alongside you, silently. (Surfacing a tab stays available as an explicit command.)

+
+你的 **agent-browser CLI** 通过 Chrome **原生消息（native messaging）** 和一个小**浏览器扩展**通信 —— 这是本机进程间通道，**无网络端口、无 token、无远程服务器**。扩展用 `chrome.debugger` 驱动你指定的标签页（在你**已登录**的 Chrome 里），再把结果交还给 CLI。全程都在你本机。
+
+![架构](assets/architecture.png)
+
+每个 `--session` 拿到**自己的彩色标签组**，多个 agent 共用同一个真实浏览器、互不干扰，也不动你自己的标签页。
+
+## 安装
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/leeguooooo/agent-browser-stealth/main/install.sh | sh
+```
+
+从最新的 [GitHub Release](https://github.com/leeguooooo/agent-browser-stealth/releases) 下载对应平台的预编译二进制，安装 `agent-browser`（以及 `abs` 别名）。无需 npm，无需 token。
+
+### 安装 AI agent skills
+
+```bash
+npx skills add leeguooooo/agent-browser-stealth
+```
+
+把 `skills/agent-browser` 拉进当前项目，让你的 AI agent 拿到正确的用法和预授权的 bash 权限。
+
+## 连接你的 Chrome
+
+**推荐 —— 浏览器扩展（一键，无弹窗）。** 从 Chrome 应用商店安装 [**agent-browser-stealth** 扩展](https://chromewebstore.google.com/detail/agent-browser-stealth/knfcmbamhjmaonkfnjhldjedeobeafmk)，再注册一次本地桥：
+
+```bash
+agent-browser extension install      # 注册原生消息 host（一次性）
+agent-browser open https://x.com/home
+```
+
+之后 `agent-browser open` 就通过**原生消息**驱动你真实、已登录的 Chrome —— 无调试端口、无 token、**永远不弹 "Allow remote debugging?"**。扩展自动更新、重启不掉，零确认（适合无人值守 / agent 场景）。
+
+<details>
+<summary>备选 —— 裸 remote-debugging 端口（会弹同意框）</summary>
+
+不装扩展时，agent-browser 退回用 CDP 连接，而 Chrome 只在带 remote-debugging 端口启动时才暴露它：
+
+```bash
+# macOS
+open -a "Google Chrome" --args --remote-debugging-port=9222
+# Linux
+google-chrome --remote-debugging-port=9222
+# Windows: 给 Chrome 快捷方式 target 加 --remote-debugging-port=9222
+```
+
+然后 `agent-browser open <url>` 自动发现端口。首次连接 **Chrome 136+ 会弹 "Allow remote debugging?"** —— 点一次 Allow（该 Chrome 会话内持续有效）。上面的扩展则完全避开这个框。
+</details>
+
+## 用法
+
+```bash
+# 连接你的 Chrome 并导航
+agent-browser open https://example.com
+
+# 一切都在你已登录的浏览器里进行
+agent-browser click "Post"
+agent-browser fill "Title" "Hello World"
+agent-browser screenshot ./page.png
+```
+
+Agent 在你的 Chrome 里操作 —— 你能实时看到开标签、加载、点击。任意时刻都能接管（比如手动过验证码），然后让 agent 继续。
+
+### 独立模式（`--launch`）
+
+```bash
+# 临时：全新空 profile —— 无 cookie 无登录（适合 CI / 测试）
+agent-browser --launch open https://example.com
+
+# 保留登录：用你真实的 Chrome profile 启动
+agent-browser --launch --profile auto open https://x.com/home
+```
+
+## 反检测
+
+连接你真实 Chrome 时，我们**零** JS 注入 —— 浏览器指纹完全是真的。指导原则是 **native CDP/Chrome 覆盖优先于 JS 谎言**：被重定义的 getter 本身可被检测，原生覆盖则不会。
+
+- `navigator.webdriver = false` 走 `Emulation.setAutomationOverride`（原生，CreepJS 类说谎检测查不出）。
+- **`Runtime.enable` 默认关闭** —— 活着的 `Runtime` 域是可被检测的 CDP 信号（patchright/rebrowser 的 "runtime leak"），即便连的是你真实 Chrome。只在你主动开启 console/错误捕获时才启用。
+
+**实测结果（连接真实 Chrome，中继路径）：**
+
+| 检测站 | 结果 |
+|---|---|
+| [CreepJS](https://abrahamjuliot.github.io/creepjs/) | **0% stealth · 0% headless**（零 override 痕迹） |
+| [bot.incolumitas.com](https://bot.incolumitas.com/) | 全部 OK（overflowTest / overrideTest / puppeteerExtraStealth / worker 一致性） |
+| [rebrowser-bot-detector](https://bot-detector.rebrowser.net/) | `runtimeEnableLeak` 🟢 · `pwInitScripts` 🟢 |
+| [bot.sannysoft.com](https://bot.sannysoft.com) | 全绿 |
+
+`--launch` 独立模式下会改用一整套隐身补丁，同样过上述检测。
+
+### 类人输入（行为隐身）
+
+指纹隐身只是一半——最强的反爬厂商（Akamai、PerimeterX、DataDome）还会给**行为**打分。点击时光标瞬移到元素正中心、没有接近轨迹、按下即抬起,这本身就是破绽,**哪怕我们的 CDP 事件是 `isTrusted`**。
+
+开启 humanize 后,光标像手在动:点击走带减速的贝塞尔曲线、落在元素内**偏离正中心**的抖动点;打字用变速的击键间隔;滚动分段缓动;拖拽走曲线。而且**自适应**——每次导航探测页面是否有已知反爬厂商(cookie/脚本/全局变量),命中就自动升到全套类人动作,普通站点保持瞬时(零开销)。
+
+页面自己的 `mousemove` 流看到的(行为检测器分析的正是这个):
+
+| | 轨迹 |
+|---|---|
+| **off**（默认） | 直线 · 死磕正中心 · 瞬时 |
+| **human** | 曲线 · 先慢后快再慢 · 落点偏移 |
+
+用 `--humanize off\|fast\|human` 或 `AGENT_BROWSER_HUMANIZE` 控制。默认 `off`,自适应检测器按页面自动升档。
+
+### 静默操作
+
+操作你的真实 Chrome 不该打断你的工作。agent **全程在后台操作**:新标签后台打开(在自己的彩色会话标签组里),**从不强制把标签拽到前台**,并用 `Emulation.setFocusEmulationEnabled` 让每个 agent 标签照常渲染、`document.hasFocus()` / `visibilityState` 仍报 `visible`。于是截图正常、页面不被降频,"标签全程隐藏"也不会变成新的机器人信号。你在自己的标签里照常工作,agent 在旁边默默干活。(想置顶某个标签仍可显式调用命令。)
+
+## 与上游的差异
+
+基于 [agent-browser v0.27.0](https://github.com/vercel-labs/agent-browser)：
+
+- **默认 auto-connect** —— `agent-browser open` 连你的 Chrome 而非启新的
+- **CDP 原生隐身** —— `Emulation.setAutomationOverride` 而非 JS 补丁
+- **双隐身模式** —— 真实 Chrome 零补丁，`--launch` 全补丁
+- **`--launch` / `--new`** —— 显式启动独立浏览器
+- **CI 自动检测** —— 设了 `CI` 环境变量时走独立模式
+
+所有上游功能（命令、快照、截图、录制、标签、会话等）保持一致。

+//! Human-like input behaviour for stealth.
+//!
+//! When agent-browser drives a real Chrome over CDP, the input events it
+//! dispatches are already `isTrusted` — but a click that teleports the cursor
+//! straight to an element's exact centre, with no approach path and zero delay
+//! between move/press/release, is a behavioural tell that advanced anti-bot
+//! vendors (Akamai, PerimeterX, DataDome) look for.
+//!
+//! This module produces **human-like motion plans** — curved, eased cursor
+//! trajectories and variable keystroke timing — as *pure data*. It performs no
+//! I/O and knows nothing about CDP: callers turn the returned steps into
+//! `Input.dispatchMouseEvent` / `dispatchKeyEvent` calls. Keeping the maths pure
+//! makes the easing/jitter/detection logic unit-testable and deterministic
+//! (every randomised value comes from a caller-supplied seed).
+//!
+//! Design (see brainstorm 2026-06-11):
+//! - Three levels: [`HumanizeLevel::Off`] (instant, today's behaviour),
+//!   `Fast` (a few cheap eased steps), `Human` (full curved trajectory + jitter).
+//! - Baseline is `Off`; the daemon escalates a session to `Human` when
+//!   [`detect_level`] spots a known anti-bot vendor on the page. `--humanize` /
+//!   `AGENT_BROWSER_HUMANIZE` force a fixed level.
+//! - Humanization only changes *how* the cursor reaches a target, never *which*
+//!   element is hit: the landing jitter stays inside the caller-provided bounds.

+   If `which -a agent-browser` shows more than one install, an old **npm/pnpm**
