feat(workflow): 复刻 ultracode 手册并修复 worktree/inline/opt-in 三处缺口

围绕 ultracode skill 审查 agent 系统一致性后：
- ultracode.ts: 用系统提示版完整 Workflow 编排手册替换中文精简版
- HIGH#1 isolation:'worktree': claudeCodeBackend.run() 用 createAgentWorktree +
  runWithCwdOverride 包裹 runAgent + finally 清理实现真正的 cwd 隔离；slug 用
  sha256(runId:agentId) 派生以匹配 cleanupStaleAgentWorktrees 清理正则
  （修 runId 为 w+base36 非 UUID 导致的泄漏盲区）；worktree.ts 注释同步修正
- HIGH#2 inline 持久化: 新增 persistInlineScript，WorkflowTool + service 两条
  inline 路径对称持久化到 .claude/workflow-runs/<runId>/script.js，返回可复用
  scriptPath（闭环 inline→编辑→scriptPath 重提迭代循环）
- HIGH#3 opt-in 分工: ultracode/WorkflowTool/effort 注明 session reminder 由
  harness 注入，repo 内无 ultracode 信号，保持 feature('WORKFLOW_SCRIPTS') +
  isEnabled 两层 gate，不自造注入
- 测试: 新增 persistInline.test.ts；扩展 claudeCodeBackend(isolation 4 用例)/
  WorkflowTool(inline)/service(scriptPath)/ultracode(harness)

含配套 workflow engine/panel 完善与 run-state-persistence design doc。
