feat(workflow): add lightweight interactive planning workflow with in-memory execution and code exploration

- Introduced `lite-plan` command for intelligent task analysis and planning.
- Implemented dynamic exploration and clarification phases based on task complexity.
- Added support for auto mode and forced exploration flags.
- Defined output artifacts and session structure for planning results.
- Enhanced execution process with context handoff to `lite-execute`.

chore(temp): create temporary memory content and import script

- Added `.temp-memory-content.txt` to store session details and execution plan.
- Implemented `temp-import-memory.cjs` to handle memory import using core-memory command.
- Ensured cleanup of temporary files after execution.

+## Objective
+为 CCW spec 系统添加独立的 category 分类字段，实现 workflow stage 标记与 keywords 的分离，支持按阶段过滤加载 spec 文档。

+<summary>Full Execution Plan (Click to expand)</summary>
+
+1. 分析当前 spec 系统实现
+2. 设计 category 分类方案 (general | exploration | planning | execution)
+3. 后端实现：
+   - spec-index-builder.ts: 添加 category 字段到 SpecIndexEntry
+   - spec-init.ts: 更新 seed documents 使用 category
+   - spec-loader.ts: 支持 category 过滤
+   - commands/spec.ts: 添加 --category 选项
+   - cli.ts: 注册 --category 选项
+4. 前端实现：
+   - api.ts: 添加 category 类型
+   - SpecCard.tsx: 显示 category badge
+   - SpecsSettingsPage.tsx: 添加 category 过滤 UI
+5. 测试所有 ccw spec 命令

+## Last Action
+成功测试所有 ccw spec 命令：
+- ccw spec help ✅
+- ccw spec init ✅
+- ccw spec rebuild ✅
+- ccw spec list ✅
+- ccw spec status ✅
+- ccw spec load --category general ✅ (仅加载 general 分类)
+- ccw spec load --category planning ✅ (仅加载 planning 分类)
+
+发现并修复 CLI 启动问题：cli.ts 中 run() 函数未被调用，已添加 run(process.argv) 调用。
+
+## Decisions
+- 添加 category 为独立字段而非混入 keywords: 清晰的职责分离，keywords 用于主题匹配，category 用于 workflow stage 过滤
+- 使用 general 作为默认值: 适用于所有阶段的通用规范
+- 前端显示 category badge: 提供可视化分类指示
+- SpecIndexEntry 增加 contentLength 字段: 由用户系统优化添加，避免重复读取文件
+
+## Constraints
+- 保持向后兼容：category 为可选字段，默认 general
+- 不修改现有 spec 文档的 keywords 语义
+
+## Dependencies
+(none)
+
+## Known Issues
+- 前端构建存在预存 TypeScript 错误（IssuePanel.tsx, IssueManagerPage.tsx），与本功能无关
+- esbuild 打包需要正确配置 --packages=external 以避免动态 require 问题
+
+## Changes Made
+- spec-index-builder.ts: 添加 SpecCategory 类型、VALID_CATEGORIES、isValidCategory()、buildEntry() 解析 category
+- spec-init.ts: SpecFrontmatter 添加 category，SEED_DOCS 使用独立 category 字段
+- spec-loader.ts: SpecLoadOptions 添加 category，filterSpecs() 支持 category 过滤
+- spec.ts: SpecOptions 添加 category，loadAction() 传递 category 到 loadSpecs
+- cli.ts: 添加 --category 选项，修复 run() 未调用问题
+- api.ts: SpecEntry 添加 category 类型
+- SpecCard.tsx: 添加 SpecCategory 类型、categoryConfig 配置、显示 category badge
+- SpecsSettingsPage.tsx: 添加 CategoryFilter 状态、categoryCounts 计算、category 过滤按钮
+
+## Pending
+(none - 功能实现完成并测试通过)
+
+## Notes
+**Category 设计思路**：
+- general: 适用于所有阶段（如编码规范）
+- exploration: 代码探索、分析、调试
+- planning: 任务规划、需求分析
+- execution: 实现、测试、部署
+
+系统级加载示例：ccw spec load --category exploration
+
+**索引验证**：
+{
+  "title": "Architecture Constraints",
+  "category": "planning",
+  "keywords": ["architecture", "module", "layer", "pattern"]
+}
+keywords 不再包含 exploration/planning/execution 标记。`;
