v0.8.11: fix P1 — export Codex sessions to cwd-based .codex-history/

Each session now exports to <session.cwd>/.codex-history/ instead of the
active VS Code workspace root. Sessions from 3decoder-experiments will land
in 3decoder-experiments/.codex-history/, collective-intelligence sessions in
collective-intelligence/.codex-history/, etc. Falls back to workspaceRoot if
cwd doesn't exist on disk.

Also fix buildFilename() to use codexSessionTitle() (which honours threadName)
instead of the old raw-message extraction that grabbed system-injected text.

+## 机器架构（必须搞清楚再动手）
+
+```

+  ├── 编译 / 打包 / git push 在这里做

+  ├── Cursor 加载插件         → C:/Users/Ph.D.Chen/.cursor/extensions/
+  └── 导出落地目录            → <workspace>/.codex-history/
+```
+
+**插件在 4090 的 Cursor 里运行，读的是 4090 的文件系统。**  
+在本地确认代码逻辑后，所有验证必须在 4090 上做，不是在本地。
+
+---
+
+## 强制验证脚手架 — 每次改动后必须跑完
+
+改动代码 → 编译 → 打包 → 安装 → **验证** 这五步缺一不可。  
+**没跑完验证就说"修好了"是放屁。**
+
+### Step 1: 编译 & 打包（本地）
+
+```bash
+cd e:/001Code/Jupyter/Claude-Code-Tools/claude-code-exporter
+npm run build 2>&1          # 必须无 error
+npm run package 2>&1        # 确认 .vsix 生成
+```
+
+### Step 2: 传到 4090 并安装（本地执行）
+
+```bash
+VERSION=$(node -p "require('./package.json').version")
+VSIX="claude-code-exporter-${VERSION}.vsix"
+
+scp -o IdentitiesOnly=yes -i ~/.ssh/id_ed25519 -o StrictHostKeyChecking=no \
+  "$VSIX" "Ph.D.Chen@4090-server:C:/Users/Ph.D.Chen/Downloads/$VSIX"
+
+# 生成并执行安装脚本
+cat > /tmp/install_cce.ps1 << EOF
+\$version = "${VERSION}"
+\$vsix    = "C:\Users\Ph.D.Chen\Downloads\claude-code-exporter-\${version}.vsix"
+\$zip     = \$vsix -replace '\.vsix$', '.zip'
+\$tmp     = "C:\Users\Ph.D.Chen\Downloads\ext-extract-cce-\${version}"
+\$extDir  = "C:\Users\Ph.D.Chen\.cursor\extensions\myoontyee.claude-code-exporter-\${version}"
+
+Copy-Item \$vsix \$zip -Force
+if (Test-Path \$tmp) { Remove-Item \$tmp -Recurse -Force }
+Expand-Archive -Force -Path \$zip -DestinationPath \$tmp
+New-Item -ItemType Directory -Force -Path \$extDir | Out-Null
+Get-ChildItem "\$tmp\extension" | ForEach-Object { Copy-Item -Recurse -Force \$_.FullName \$extDir }
+Write-Host "Installed: \$extDir"
+EOF
+
+scp -o IdentitiesOnly=yes -i ~/.ssh/id_ed25519 -o StrictHostKeyChecking=no \
+  /tmp/install_cce.ps1 "Ph.D.Chen@4090-server:C:/Users/Ph.D.Chen/install_cce.ps1"
+
+ssh -o IdentitiesOnly=yes -i ~/.ssh/id_ed25519 -o StrictHostKeyChecking=no \
+  "Ph.D.Chen@4090-server" "powershell -NoProfile -File C:/Users/Ph.D.Chen/install_cce.ps1"
+```
+
+### Step 3: 验证 session_index 可读（4090）
+
+```bash
+ssh -o IdentitiesOnly=yes -i ~/.ssh/id_ed25519 -o StrictHostKeyChecking=no \
+  "Ph.D.Chen@4090-server" \
+  "powershell -Command \"Get-Content 'C:\Users\Ph.D.Chen\.codex\session_index.jsonl' | Select-Object -First 5\""
+```
+
+期望：能看到含 `thread_name` 的 JSON 行。如果文件不存在或为空，标题修复根本不会生效，不要继续。
+
+### Step 4: 验证导出文件名（4090 上手动操作 + SSH 确认）
+
+**4090 上操作：**
+1. 重启 4090 的 Cursor（不是 Codex APP，是 Cursor）
+2. 打开 Claude Code Exporter 的 Sessions 面板
+3. 找到目标 Codex 会话，点 Export 按钮（re-export 会覆盖旧文件名）
+
+**SSH 确认结果：**
+```bash
+# 替换为实际 workspace 路径
+ssh -o IdentitiesOnly=yes -i ~/.ssh/id_ed25519 -o StrictHostKeyChecking=no \
+  "Ph.D.Chen@4090-server" \
+  "powershell -Command \"Get-ChildItem 'E:\001Code\Jupyter\000PhD\I_CT\3decoder-experiments\.codex-history' -Filter '*.md' | Select-Object Name\""
+```
+
+期望：文件名里的标题段是真实对话标题（如"核查最新聊天并检查075实验代码问题"），不是 `#-AGENTS.md-instructions` 或乱码。
+
+**只有看到正确文件名才算验证通过。**
+
+### Step 5: 确认后才能 git push & 版本号升级
+
+验证通过之前不要 push，不要升版本号，不要说"已修好"。
+
+---
+
+## 已知 Bug 优先级
+
+| 优先级 | 问题 | 状态 |
+|--------|------|------|
+| P0 | Codex 会话标题乱（AGENTS.md 注入） | v0.8.10 已修，待验证 |
+| P1 | CodexWatcher 把所有会话都导出到当前 workspace，不按 cwd 分类 | 未修 |
+
+P1 直接导致用户在正确的项目目录下找不到对应会话的导出文件。不要在 P0 验证通过前就去改 P1，也不要在 P1 未修的情况下假装问题解决了。
+
+---
+
+## 禁止行为
+
+- 改完代码 build 成功就宣布"修好了" — build 成功只说明编译通过，不代表功能正确
+- 在本地验证文件路径 / 标题逻辑 — 插件在 4090 跑，本地验不到真实数据
+- 跳过 Step 4 的手动 re-export — 现有旧文件名不会自动更新，必须触发一次 export
+- 发现新 bug 后立刻跳过去修 — 先把当前 bug 闭环验证，再开新问题
