feat(storage): support configurable runtime output directory (#2127)

* feat(storage): support configurable runtime output directory (#2014)

Add `advanced.runtimeOutputDir` setting and `QWEN_RUNTIME_DIR` env var
to redirect runtime output (temp files, debug logs, session data, todos,
insights) to a custom directory while keeping config files at ~/.qwen.

- Introduce `Storage.setRuntimeBaseDir()` / `getRuntimeBaseDir()` with
  tilde expansion and relative path resolution
- Add `AsyncLocalStorage`-based `runWithRuntimeBaseDir()` for concurrent
  session isolation in ACP integration
- Update all runtime path methods to use `getRuntimeBaseDir()` instead
  of `getGlobalQwenDir()` (temp, debug, ide, projects, history dirs)
- Config paths (settings, oauth, installation_id, etc.) remain pinned
  to `~/.qwen` regardless of runtime dir configuration
- Add comprehensive tests covering path resolution, env var priority,
  async context isolation, and config path stability

* fix(core/storage): 支持 Windows 风格波浪号路径

扩展 setRuntimeBaseDir 以支持 Windows 风格的波浪号路径 (~\),
使用统一的路径分割逻辑处理 Unix 和 Windows 风格的路径分隔符

* feat(cli): add runtime output directory configuration support

* fix(core): update test to use getUserSkillsDirs method

Update storage.test.ts to call getUserSkillsDirs() instead of the
non-existent getUserSkillsDir() method. The method was renamed to
return an array of skill directories.

* fix(core/todoWrite): use path.join for cross-platform path assertion in test

Replace hardcoded forward-slash path `.qwen/todos/` with `path.join('.qwen', 'todos')` to fix Windows CI failure where paths use backslashes.
