fix(build): include browser.rs clear_viewport/via_relay (#47) + cargo fmt

v1.5.24 (d5cd9cd) shipped a commands.rs caller of `clear_viewport` but not the
browser.rs method it lives in (a concurrent in-progress #47 viewport/resize edit
was only partly staged), so main didn't compile and the format check failed.
Commit the matching browser.rs method + via_relay() helper and run cargo fmt.
Full tree builds; 863 tests pass.

+## Site adapters — turn a website into a structured-data CLI
+
+Most "read GitHub issues" / "search Reddit" / "get my Bilibili feed" tasks don't
+need clicking and screenshotting at all — the site already has a JSON API behind
+its own login. A **site adapter** is a tiny JS function that calls that API *from
+inside your logged-in tab* (your cookies, same-origin `fetch`, the site's own
+modules) and returns clean JSON. The site can't tell it apart from you, because it
+*is* you.
+
+chrome-use ships none of these adapters — `site update` fetches the community
+[**bb-sites**](https://github.com/epiral/bb-sites) pack at runtime (like a package
+manager pulling a dependency), then runs them over chrome-use's stealth transport:
+
+```bash
+chrome-use site update                          # fetch the adapter pack (~145 commands)
+chrome-use site list                            # github/issues, reddit/search, bilibili/feed, …
+chrome-use site info github/issues              # see an adapter's args + domain
+
+# Run one — navigates to the site (reusing the tab if you're already there) and returns JSON
+chrome-use site github/issues epiral/bb-browser --json
+chrome-use site reddit/search "rust async" --json
+chrome-use site bilibili/feed --json            # works because it's your logged-in session
+```
+
+Positional args fill the adapter's declared args in order; `--key value` overrides
+by name. Adapters are authored by the bb-sites community and remain their authors'
+property — chrome-use just runs them.
+
+**Auto-sync + auto-suggest.** You rarely type `site update` yourself: chrome-use
+syncs the pack on first use and refreshes it weekly in the background (tune with
+`AGENT_BROWSER_SITES_TTL_DAYS`, disable with `AGENT_BROWSER_SITES_NO_AUTO_UPDATE=1`).
+And when you `open`/`snapshot` a page whose domain has adapters, chrome-use surfaces
+them right in the output — a `💡 site adapters for <domain>` line, plus a
+`siteAdapters` field under `--json` — so an agent reaches for the structured-data
+adapter instead of scraping the DOM:
+
+```text
+$ chrome-use open https://github.com
+💡 site adapters for github.com — prefer these for structured data:
+   github/issues, github/me, github/repo, …
+   e.g. chrome-use site github/issues --json

+## 站点适配器 —— 把一个网站变成「结构化数据 CLI」
+
+大多数「读 GitHub issue」「搜 Reddit」「拉我的 B 站动态」这类任务，根本不需要点击 +
+截图 —— 网站登录态背后本来就有 JSON 接口。**站点适配器**就是一小段 JS 函数，它在你
+**已登录的标签页内**调用那个接口（用你的 cookie、同源 `fetch`、网站自己的模块），返回
+干净的 JSON。网站分辨不出它和你的区别，因为它**就是你**。
+
+chrome-use 本身不附带任何适配器 —— `site update` 会在运行时拉取社区的
+[**bb-sites**](https://github.com/epiral/bb-sites) 适配器包（就像包管理器拉依赖），
+然后在 chrome-use 的隐身通道上运行它们：
+
+```bash
+chrome-use site update                          # 拉取适配器包（约 145 条命令）
+chrome-use site list                            # github/issues、reddit/search、bilibili/feed…
+chrome-use site info github/issues              # 查看某个适配器的参数 + 域名
+
+# 运行一个 —— 会导航到对应站点（已在该站点则复用当前标签页）并返回 JSON

+chrome-use site reddit/search "rust async" --json
+chrome-use site bilibili/feed --json            # 能用，因为走的是你的登录态
+```
+
+位置参数按适配器声明的参数顺序填入；`--key value` 按名覆盖。适配器由 bb-sites 社区编写、
+版权归各自作者所有 —— chrome-use 只负责运行它们。
+
+**自动同步 + 自动提示。** 你基本不用手动 `site update`:chrome-use 首次使用时自动拉取,
+之后每周后台刷新一次(`AGENT_BROWSER_SITES_TTL_DAYS` 调周期,`AGENT_BROWSER_SITES_NO_AUTO_UPDATE=1`
+关闭)。而当你 `open`/`snapshot` 一个有适配器的域名时,chrome-use 会在输出里直接把可用命令
+亮出来 —— 一行 `💡 site adapters for <域名>`,`--json` 下则是 `siteAdapters` 字段 —— 这样
+agent 会直接改用结构化适配器,而不是去扒 DOM:
+
+```text
+$ chrome-use open https://github.com
+💡 site adapters for github.com — prefer these for structured data:
+   github/issues, github/me, github/repo, …
+   e.g. chrome-use site github/issues --json
+✓ GitHub
+```
+
+## 自动化测试（`chrome-use test`）
+
+把反复的「打开它、点一圈、看对不对」变成**可重跑的测试套件** —— 前端的单元测试。用 YAML 写用例；步骤复用 chrome-use 自己的命令，断言编译成一次检查：
+
+```yaml
+# smoke.yaml
+suite: chatgpt smoke
+setup:
+  - account: chatgpt/huayue          # 注入一个 cookie-use 登录（可选）
+cases:
+  - name: home loads logged in
+    steps:
+      - open: https://chatgpt.com/
+      - wait: { load: networkidle }
+    assert:
+      - url: { contains: chatgpt.com }
+      - visible: "#prompt-textarea"
+```
+
+```bash
+chrome-use test smoke.yaml                     # 启动隔离浏览器，跑用例
+chrome-use test smoke.yaml --session default   # …或对你已连接的 Chrome 跑
+```
+
+```
+suite: chatgpt smoke  (session cu-test)
+  ✓ home loads logged in   1.2s
+  ✗ composer takes text    0.8s
+      assert text "#prompt-textarea" contains "hi" → got ""
+      ↳ cu-test-artifacts/composer-takes-text.png
+2 cases · 1 passed · 1 failed
+```
+
+任一用例失败时退出码非零（可直接丢进 CI），失败用例会存截图。断言：`url` · `visible` · `hidden` · `text` · `count` · `eval`。步骤：`open` · `click` · `fill` · `type` · `press` · `wait` · `scroll` · `eval`。完整指南：`chrome-use skills get test`。发现回归？加个用例 —— 用得越多，套件越值钱。

+//! Site adapters: turn any website into a structured-data CLI by running a small
+//! per-command JS adapter inside your real, logged-in browser tab (it reuses the
+//! site's cookies / same-origin fetch / its own webpack modules — the site thinks
+//! it's you, because it is).
+//!
+//! The adapter format is the community **bb-sites** convention
+//! (<https://github.com/epiral/bb-sites>): one `.js` file per command, a
+//! `/* @meta {...} */` JSON header (name, description, domain, args), then an
+//! `async function(args){ ... return {...} }`. chrome-use ships none of those
+//! adapters — `chrome-use site update` fetches the upstream repo at runtime into
+//! `~/.chrome-use/sites` (like a package manager pulling a dependency), so the
+//! adapters stay the property of their authors. Running an adapter navigates to
+//! its `@meta.domain` and `eval`s the function in the site's own logged-in page.

+
+Before you `open` + `snapshot` + click your way through GitHub/Reddit/Bilibili/etc.,
+check whether a **site adapter** already exists. An adapter is a community-written JS
+function that hits the site's own JSON API *from inside your logged-in tab* and returns
+clean structured data — no clicking, no scraping, no screenshots. It's the same idea as
+`eval`, packaged per-site.
+
+```bash
+chrome-use site update                       # one-time: fetch the adapter pack (~145 cmds)
+chrome-use site list                         # what's installed (github/issues, reddit/search, …)

+chrome-use site github/issues owner/repo --json   # run it → JSON (navigates there for you)
+```
+
+- Positional args fill the adapter's declared args **in order**; `--key value` overrides by name.
+- It navigates to the adapter's domain (reusing the current tab if you're already on it), so

+- If no adapter fits, fall back to the normal `snapshot`/`eval` loop. Adapters come from the

 extension (each with a distinct `--session`), not raw `--cdp`.
 
+Each session owns its own tab group and assigns its own `t<N>` indices (the same
+physical tab is `t8` in one session, `t1` in another), so `t<N>` is **not** a
+stable cross-session handle. To reach a *specific* tab from another session — e.g.
+a tab that was filled in a session whose handle later died — use the **stable CDP
+`targetId`**:
+
+```bash
+chrome-use tab list --full --session B   # re-syncs live tabs; prints `target: <id>` per row
+chrome-use tab <targetId> --session B    # adopt that exact tab, NO reload (state preserved)
+```
+
+`tab list` re-discovers the live tab set on every call, so a fresh session sees
+tabs other sessions opened (and re-attached ones), not just its own. Adopting by
+`targetId` lands session B on the stranded tab without reloading it, so a
+half-filled form survives. Still, the simplest recovery for a session whose own
+tab died is to recover *that* session (reload / re-`open` / `daemon restart`).
+
+To avoid piling up duplicate tabs when you re-`open` the same entry URL on
+rebind, pass **`--reuse-tab`**: if a tab already shows that URL (matched by
+origin+path), it switches to it instead of spawning a new one.
