feat(web): protect launcher dashboard with token and SPA login (#1953)

Add token-based authentication for the Launcher's embedded Web Dashboard.

- Ephemeral token generated in-memory each run (or via PICOCLAW_LAUNCHER_TOKEN env var)
- HMAC-SHA256 session cookie (HttpOnly, SameSite=Lax, Secure when HTTPS)
- Bearer token support for API/script access
- Rate limiting on login (10 attempts/IP/min)
- Referrer-Policy: no-referrer on all responses
- POST-only logout with JSON content-type (CSRF-safe)
- System tray "Copy dashboard token" action
- Login page shows contextual help (console/tray/log file path)
- Path traversal protection via path.Clean
- X-Forwarded-Host/Port/Proto support for reverse proxy deployments
- Full i18n support (English, Chinese)

+### Web launcher dashboard
+
+**picoclaw-launcher** serves a browser UI that requires sign-in first. By default, the **dashboard token** and **session signing key** are **generated in memory on each start** (a new random token after every restart). Set **`PICOCLAW_LAUNCHER_TOKEN`** to pin a fixed token for that process (startup logs do not print the secret when this env var is used).
+
+**Where to read the token**: In **console mode** (`-console`), it is printed at startup. In **tray / GUI mode**, use the tray action **Copy dashboard token**, and check **`$PICOCLAW_HOME/logs/launcher.log`** (typically `~/.picoclaw/logs/launcher.log` if `PICOCLAW_HOME` is unset) for the random token logged on startup. The login page shows hints that match how the launcher is running (including the absolute log path); **responses do not include the token itself**.
+
+- **Config file**: Same directory as `config.json` (or the file pointed to by `PICOCLAW_CONFIG`). The launcher-specific file is `launcher-config.json`.
+- **Sign-in and links**: Enter the token on the login page, or open with `?token=` when the browser is launched automatically. All responses include **`Referrer-Policy: no-referrer`** to reduce leakage of `token` via the `Referer` header.
+- **Sign-out**: Use **`POST /api/auth/logout`** with **`Content-Type: application/json`** (body may be `{}`). Do not rely on a GET URL for logout (CSRF-safe pattern).
+- **Brute-force**: **`POST /api/auth/login`** is **rate-limited per client IP per minute** (HTTP 429 when exceeded).
+- **Session lifetime**: The HttpOnly session cookie lasts about **7 days** by default; sign in again with the token after it expires.

+
+**到哪里找口令**：**控制台模式**（`-console`）请看启动时的终端输出；**托盘 / GUI 模式**可使用托盘菜单中的「复制控制台口令」，并在 **`$PICOCLAW_HOME/logs/launcher.log`**（未设置 `PICOCLAW_HOME` 时一般为 `~/.picoclaw/logs/launcher.log`）中查看本次启动写入的随机口令。登录页在未登录时会根据当前运行方式展示提示（含日志文件绝对路径等；**接口与页面均不会返回口令本身**）。
+
+- **配置文件**：与 `config.json` 同一目录（若设置了 `PICOCLAW_CONFIG`，则与它所指的文件同目录）。启动器专用文件名为 `launcher-config.json`。
+- **登录与链接**：在登录页输入口令；自动打开浏览器时可在 URL 上使用 `?token=`。全站响应携带 **`Referrer-Policy: no-referrer`**，减轻 `token` 经 `Referer` 头泄露的风险。
+- **退出登录**：应使用 **`POST /api/auth/logout`**，且请求头为 **`Content-Type: application/json`**（请求体可为 `{}`），勿使用可被第三方页面触发的 GET 链接登出。
+- **暴力尝试**：`POST /api/auth/login` 对同一远程地址有 **每分钟尝试次数上限**（超限返回 HTTP 429）。
+- **会话时长**：登录后的 HttpOnly 会话 Cookie 默认约 **7 天**有效，到期需重新用口令登录。
