internal/cli：stalled 與 xrefs 命令接線，完成 #7 CLI 層（堆疊於 #23）

- workflow 新增 StalledSource 介面（Source＋CurrentUser＋GetIssue）與
  高階入口 RunStalled／ResolveIssueXrefs（xrefs 輸出附 source 出處）
- APIClient 補上 StalledSource 面向（GetIssue／TryGetIssue 等）
- CLI 新增 teai stalled [--hours N]（JSON 與 gitea.py 位元組相容：
  停用 HTML 轉義、縮排 2）與 teai xrefs <owner>/<repo> <number>
  （404 → exit 3）；table 模式 stalled_hours 定點一位小數
- 接線層與 workflow 層單元測試（注入假資料源、固定時刻）
- README 狀態行更新

驗證：go build／vet／test 全綠；對真實 API 並行掃描，stalled 輸出
與 gitea.py 位元組一致（2169 bytes）；xrefs 邊界案例（PR#50／
issue#49 略過、CJK 緊鄰、跨倉庫 owner/repo#N）與 Python 版一致。

 ## 安裝與建置
 
-需要 Go 1.26 以上。
+### 需求
+
+- **Go 1.26 以上**（`go version` 確認；本倉庫僅用標準庫，離線可建置）
+- **git**
+- Gitea 帳號的 **API token**（設定階段使用；在 Gitea「設定 → 應用程式」產生）
+
+### 從原始碼建置
 
 ```sh
+git clone https://gitea.alterminal.com/alterminal/teai.git
+cd teai
 go build -o teai ./cmd/teai
+install -Dm755 teai ~/.local/bin/teai   # 或複製到任何 PATH 內目錄
+teai version                             # 驗證：teai version 0.1.0-dev
 ```
 
+也可以直接裝進 `GOBIN`（預設 `~/go/bin`；該目錄已在 PATH 時最省事）：
+
+```sh
+go install ./cmd/teai
+```
+
+> **注意：** `go install gitea.alterminal.com/alterminal/teai/cmd/teai@latest` 目前**不可用**——
+> module 尚未發佈任何 tag，`@latest` 會解析到任意中繼 commit（且 #21 修復前 main 建置失敗）。
+> 請在 clone 目錄內以版本控制的方式建置；發佈 tag 後再提供 `teai@<version>` 安裝路徑。
+
+### 登入設定（首次使用）
+
+teai 與 `tea` 共用同一份組態檔；若 `tea whoami` 已可正常輸出，可跳過本節。
+
+```sh
+teai login add --url https://gitea.alterminal.com
+# 未給 --token 時自 stdin 讀一行：貼上 token 後按 Enter（不會進 shell 歷史）
+teai whoami    # 驗證：應輸出 {"username":"<你的帳號>"}
+```
+
+- token 驗證失敗（HTTP 401）不會寫入組態，結束碼 3。
+- 組態檔：`--config`／`TEA_CONFIG` 指定，預設 `~/.config/tea/config.yml`；teai 採行級編輯，
+  不會改壞 tea 也在使用的欄位，檔案權限 `0600`。
+- 多站台以 `--name` 區分、`teai login default <名稱>` 切換預設；詳見下方 [`teai login`](#teai-login--管理登入) 一節。
