fix(tool): Windows UNC 路径规范 — PathValidator 路径比较一致性

- with_workspace() 对 workspace_root 做 canonicalize，确保与
  resolve_and_validate 产出的 canonical 路径格式一致
- 新增 normalize_windows_path() 剥离 \?\ 前缀，解决 Windows 上
  starts_with 比较失败问题
- check_blocked/check_allowed 统一使用规范化路径比较

+| 这个改动涉及一个必须始终成立的约束？ | 对应模块页"代码逻辑"节的 ⚡ 不变量 |
+| 这个改动改变了功能链路（前端→后端的完整路径）？ | `wiki/feature-map.md` 索引表 |

+## 15. Karpathy 编码原则
+
+> 源自 Andrej Karpathy 对 LLM 编码问题的观察。偏向谨慎而非速度，简单任务可灵活判断。
+
+### 15.1 Think Before Coding
+
+**Don't assume. Don't hide confusion. Surface tradeoffs.**
+
+- State assumptions explicitly. If uncertain, ask.
+- If multiple interpretations exist, present them — don't pick silently.
+- If a simpler approach exists, say so. Push back when warranted.
+- If something is unclear, stop. Name what's confusing. Ask.
+
+### 15.2 Simplicity First
+
+**Minimum code that solves the problem. Nothing speculative.**
+
+- No features beyond what was asked.
+- No abstractions for single-use code.
+- No "flexibility" or "configurability" that wasn't requested.
+- No error handling for impossible scenarios.
+- If you write 200 lines and it could be 50, rewrite it.
+
+Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.
+
+### 15.3 Surgical Changes
+
+**Touch only what you must. Clean up only your own mess.**
+
+When editing existing code:
+
+- Don't "improve" adjacent code, comments, or formatting.
+- Don't refactor things that aren't broken.
+- Match existing style, even if you'd do it differently.
+- If you notice unrelated dead code, mention it — don't delete it.
+
+When your changes create orphans:
+
+- Remove imports/variables/functions that YOUR changes made unused.
+- Don't remove pre-existing dead code unless asked.
+
+The test: Every changed line should trace directly to the user's request.
+
+### 15.4 Goal-Driven Execution
+
+**Define success criteria. Loop until verified.**
+
+Transform tasks into verifiable goals:
+
+- "Add validation" → "Write tests for invalid inputs, then make them pass"
+- "Fix the bug" → "Write a test that reproduces it, then make it pass"
+- "Refactor X" → "Ensure tests pass before and after"
+
+For multi-step tasks, state a brief plan:
+
+```
+1. [Step] → verify: [check]
+2. [Step] → verify: [check]
+3. [Step] → verify: [check]
+```
+
+Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.
+
+---
+
+**These guidelines are working if:** fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.

+2. **experiences**: 仅提取明确的"问题→解决"模式，要求有清晰的痛点和步骤，confidence >= 0.6
+3. **profile_signals**: 从对话中推断用户画像信息，只在有明确信号时填写，留空则不填
+4. **identity**: 检测用户是否给助手命名(如"你叫X"/"以后叫你X"/"你的名字是X")或自我介绍(如"我叫X"/"我的名字是X")，填入 agent_name 或 user_name 字段
+5. 每个字段都要有实际内容，不确定的宁可省略

+//! Daily Report Hand — generates a personalized daily briefing.
+//!
+//! System hand (`_daily_report`) triggered by SchedulerService at 09:00 cron.
+//! Produces a Markdown daily report containing:
+//!   1. Yesterday's conversation summary
+//!   2. Unresolved pain points follow-up
+//!   3. Recent experience highlights
+//!   4. Industry-specific daily reminder
+//!
+//! The caller (SchedulerService or Tauri command) is responsible for:
+//!   - Assembling input data (trajectory summary, pain points, experiences)
+//!   - Emitting `daily-report:ready` Tauri event after execution
+//!   - Persisting the report to VikingStorage
