refactor: add codemap- prefix to skill names for namespace isolation

Rename skill directories and frontmatter names:
  scan → codemap-scan, load → codemap-load, update → codemap-update,
  query → codemap-query, impact → codemap-impact

Keeps auto-triggering capability while avoiding name collisions.

 ### 问题
 
-当前 5 个功能（scan、load、update、query、impact）全部实现为 skills。存在以下问题：
-- 名称冲突风险：`scan`、`load`、`update`、`query` 过于通用，可能与其他插件冲突
-- 误触发：skill 根据 description 关键词自动激活，"扫描"、"查找"、"更新" 在日常对话中极其常见，可能在无关上下文中触发
-- 不可控：用户讨论非 CodeMap 相关的 scan/query 时也可能被激活
+原 skill 名称（scan、load、update、query、impact）过于通用，可能与其他插件冲突或在无关对话中误触发。
 
-### 方案：Commands + Hook 混合模式
+### 方案（已实施）
 
-**Commands（明确操作）：**
+保留 skills 自动触发能力，通过 `codemap-` 前缀实现命名空间隔离：
 
-将 5 个 skill 转为 commands，获得 `codemap:` 命名空间隔离：
+| 原名 | 新名 |
+|------|------|
+| `scan` | `codemap-scan` |
+| `load` | `codemap-load` |
+| `update` | `codemap-update` |
+| `query` | `codemap-query` |
+| `impact` | `codemap-impact` |
 
-| 当前 (skill) | 迁移后 (command) | 说明 |
-|-------------|-----------------|------|
-| `/scan` | `/codemap:scan` | 全量扫描 |
-| `/load` | `/codemap:load` | 加载图谱 |
-| `/update` | `/codemap:update` | 增量更新 |
-| `/query` | `/codemap:query` | 符号查询 |
-| `/impact` | `/codemap:impact` | 影响分析 |
+### 待办：SessionStart Hook
 
-文件变更：`ccplugin/skills/*/SKILL.md` → `ccplugin/commands/*.md`，调整 frontmatter 格式。
-
-**Hook（自动触发）：**
-
-添加 `SessionStart` hook 实现自动上下文恢复：
-
-```json
-{
-  "hooks": {
-    "SessionStart": [{
-      "hooks": [{
-        "type": "command",
-        "command": "bash \"${CLAUDE_PLUGIN_ROOT}/scripts/session-start.sh\"",
-        "timeout": 10,
-        "statusMessage": "CodeMap: 检测项目图谱..."
-      }]
-    }]
-  }
-}
-```
-
-`session-start.sh` 逻辑：
-1. 检测当前工作目录是否存在 `.codemap/graph.json`
-2. 如果存在 → 输出提示信息，建议用户使用 `/codemap:load` 加载图谱
-3. 如果不存在 → 静默退出，不干扰用户
-
-这样既实现了自动触发（提示用户图谱可用），又避免了 skill 误触发的问题。
-
-### 迁移状态
-
-- [ ] 将 5 个 skills 转为 commands
-- [ ] 创建 SessionStart hook 脚本
-- [ ] 创建 hooks/hooks.json
-- [ ] 更新 README 中的 skill 相关文档
-- [ ] 测试安装验证
+后续可添加 `SessionStart` hook 实现会话启动时自动检测 `.codemap/` 并提示加载。
