feat(cli): 添加 --rule 选项支持模板自动发现

重构 ccw cli 模板系统：

- 新增 template-discovery.ts 模块，支持扁平化模板自动发现
- 添加 --rule <template> 选项，自动加载 protocol 和 template
- 模板目录从嵌套结构 (prompts/category/file.txt) 迁移到扁平结构 (prompts/category-function.txt)
- 更新所有 agent/command 文件，使用 $PROTO $TMPL 环境变量替代 $(cat ...) 模式
- 支持模糊匹配：--rule 02-review-architecture 可匹配 analysis-review-architecture.txt

其他更新：
- Dashboard: 添加 Claude Manager 和 Issue Manager 页面
- Codex-lens: 增强 chain_search 和 clustering 模块

+# Rule Template: Implementation Patterns
+
+## Variables

+# {TECH_STACK_NAME} Implementation Patterns
+
+## Common Patterns
+
+[With code examples from Exa research]
+
+### Pattern 1: [Name]
+```{lang}
+// Example code
+```
+**When to use**: [Context]
+**Benefits**: [Why this pattern]
+
+### Pattern 2: [Name]
+...
+
+## Anti-Patterns to Avoid
+
+[Common mistakes with examples]
+
+### Anti-Pattern 1: [Name]
+```{lang}
+// Bad example
+```
+**Problem**: [Why it's bad]
+**Solution**: [Better approach]
+
+## Error Handling
+
+[Error handling conventions]
+- Error types and hierarchy
+- Try-catch patterns
+- Error propagation
+- Logging practices
+
+## Async Patterns
+
+[Asynchronous code conventions - if applicable]
+- Promise handling
+- Async/await usage
+- Concurrency patterns
+- Error handling in async code
+
+## State Management
+
+[State handling patterns]
+- Local state patterns
+- Shared state approaches
+- Immutability practices
+```
+
+## Content Guidelines
+
+- Focus on source code implementation
+- Provide concrete code examples
+- Show both good and bad patterns
+- Include context for when to apply each pattern
