feat(profile): 新增用户画像统计快捷命令

新增只读 profile 命令组，封装此前无 shortcut 覆盖的 GitLink 用户画像统计接口： profile +ability -> /users/{user}/statistics/develop profile +role -> /users/{user}/statistics/role profile +major -> /users/{user}/statistics/major profile +activity -> /users/{user}/statistics/activity profile +contribution -> /users/{user}/headmaps 省略 --user 时默认通过 /users/me 解析当前认证用户。统计命令支持 --start-time/--end-time 时间窗口， +contribution 支持 --year 参数。包含单元测试、中英双语 i18n 帮助文本、README 更新及变更说明文档。

+### User Profile
+
+`profile` surfaces GitLink's native user statistics (ability, role, major, activity,
+contribution). When `--user` is omitted it defaults to the authenticated user.
+
+```bash
+# Development ability scores + language breakdown
+gitlink-cli profile +ability --user zhangsan
+
+# Role positioning / major (discipline) categories
+gitlink-cli profile +role --user zhangsan
+gitlink-cli profile +major --user zhangsan
+
+# Ability within a time window (Unix timestamps)
+gitlink-cli profile +ability --user zhangsan --start-time 1704067200 --end-time 1735689600
+
+# Recent activity (issues / PRs / commits per day) for the current user
+gitlink-cli profile +activity
+
+# Contribution heatmap for a given year
+gitlink-cli profile +contribution --user zhangsan --year 2025
+```

+### 用户画像
+
+`profile` 暴露 GitLink 原生的用户画像统计（开发能力、角色定位、专业定位、近期活动、贡献热力图）。
+省略 `--user` 时默认使用当前认证用户。
+
+```bash
+# 开发能力评分 + 语言分布
+gitlink-cli profile +ability --user zhangsan
+
+# 角色定位 / 专业（学科）定位
+gitlink-cli profile +role --user zhangsan
+gitlink-cli profile +major --user zhangsan

+# 指定时间范围的开发能力（Unix 时间戳）
+gitlink-cli profile +ability --user zhangsan --start-time 1704067200 --end-time 1735689600
+
+# 当前用户的近期活动（每日 疑修 / 合并请求 / 提交）

+# Profile (User Statistics) Shortcuts
+
+## Summary
+
+Adds a new read-only `profile` shortcut group that wraps GitLink's user statistics
+APIs (development ability, role positioning, major/discipline, recent activity, and
+contribution heatmap). These endpoints previously had no shortcut coverage, forcing
+agents to fall back to Raw API calls — the `gitlink-contributor-insight` skill even
+documents `user +stats`/`user +heatmap` as unavailable. The `profile` group surfaces
+the platform's native portrait data directly, powering "research subject portrait"
+scenarios.
+
+## Commands
+
+| Command | Purpose | Endpoint |
+|---------|---------|----------|
+| `gitlink-cli profile +ability` | Development ability scores + language breakdown | `GET /users/{user}/statistics/develop` |
+| `gitlink-cli profile +role` | Role positioning | `GET /users/{user}/statistics/role` |
+| `gitlink-cli profile +major` | Major/discipline categories | `GET /users/{user}/statistics/major` |
+| `gitlink-cli profile +activity` | Recent activity (issues/PRs/commits per day) | `GET /users/{user}/statistics/activity` |
+| `gitlink-cli profile +contribution` | Contribution heatmap | `GET /users/{user}/headmaps` |
+
+## Behaviour
+
+- `--user`/`-u` selects the target user. When omitted, the user is resolved from the
+  authenticated account via `/users/me`, so `gitlink-cli profile +ability` works with
+  no arguments.
+- `+ability`, `+role`, and `+major` accept optional `--start-time` / `--end-time`
+  (Unix timestamps) that map to the `start_time` / `end_time` query parameters.
+- `+contribution` accepts an optional `--year` query parameter.
+
+## Tests
+
+Unit tests cover endpoint paths for every subcommand, the `start_time`/`end_time` and
+`year` query parameter mapping, current-user fallback via `/users/me`, the missing-login
+error path, and HTTP error handling.
+
+## 中文说明
+
+### 变更内容
+
+- 新增 `profile` 命令组，封装 GitLink 用户画像统计接口：
+  - `profile +ability` 开发能力评分（影响力/贡献度/活跃度/项目经验/语言能力）及语言分布
+  - `profile +role` 角色定位
+  - `profile +major` 专业/学科定位（如深度学习、量子计算）
+  - `profile +activity` 近期活动统计（每日疑修/合并请求/提交数量）
+  - `profile +contribution` 贡献热力图
+- `--user`/`-u` 指定目标用户；缺省时通过 `/users/me` 解析为当前认证用户。
+- `+ability`/`+role`/`+major` 支持 `--start-time`/`--end-time`（Unix 时间戳）。
+- `+contribution` 支持 `--year`。
+
+### 价值
+
+这些接口此前无任何 shortcut 封装，`gitlink-contributor-insight` Skill 甚至将
+`user +stats`/`user +heatmap` 标注为"不可用"并改用 PR 时间戳手工推算。`profile`
+命令组直接暴露平台原生画像数据，为"科研主体画像"等场景提供数据底座。
