feat: Add explorer and synthesizer roles with commands for codebase exploration and synthesis

- Implemented `explorer` role for parallel codebase exploration using `cli-explore-agent`.
- Created `explore.md` command documentation detailing exploration strategy and execution steps.
- Established `synthesizer` role for integrating insights from explorations, analyses, and discussions.
- Developed `synthesize.md` command documentation outlining synthesis strategy and output format.
- Configured team settings in `team-config.json` to support new roles and pipeline modes.
- Added regression test for CodexLens bootstrap fallback to ensure robustness in error handling.

+# Team Ultra Analyze
+
+深度协作分析团队技能。将单体分析工作流拆分为 5 角色协作：探索→分析→讨论→综合。支持 Quick/Standard/Deep 三种管道模式，通过讨论循环实现用户引导的渐进式理解深化。所有成员通过 `--role=xxx` 路由到角色执行逻辑。

+
+**设计原则**: role.md 保留 Phase 1（Task Discovery）和 Phase 5（Report）内联。Phase 2-4 根据复杂度决定内联或委派到 `commands/*.md`。
+
+## Role Router
+
+### Input Parsing
+
+Parse `$ARGUMENTS` to extract `--role`:
+
+```javascript
+const args = "$ARGUMENTS"
+const roleMatch = args.match(/--role[=\s]+(\w+)/)
+
+if (!roleMatch) {
+  throw new Error("Missing --role argument. Available roles: coordinator, explorer, analyst, discussant, synthesizer")
+}
+
+const role = roleMatch[1]
+const teamName = args.match(/--team[=\s]+([\w-]+)/)?.[1] || "ultra-analyze"
+```
+
+### Role Dispatch
+
+```javascript
+const VALID_ROLES = {
+  "coordinator":  { file: "roles/coordinator/role.md",  prefix: null },
+  "explorer":     { file: "roles/explorer/role.md",     prefix: "EXPLORE" },
+  "analyst":      { file: "roles/analyst/role.md",       prefix: "ANALYZE" },
+  "discussant":   { file: "roles/discussant/role.md",    prefix: "DISCUSS" },
+  "synthesizer":  { file: "roles/synthesizer/role.md",   prefix: "SYNTH" }
+}
+
+if (!VALID_ROLES[role]) {
+  throw new Error(`Unknown role: ${role}. Available: ${Object.keys(VALID_ROLES).join(', ')}`)
+}
+
+// Read and execute role-specific logic
+Read(VALID_ROLES[role].file)
+// → Execute the 5-phase process defined in that file
+```
+
+### Available Roles
+
+| Role | Task Prefix | Responsibility | Role File |
+|------|-------------|----------------|-----------|
+| `coordinator` | N/A | 话题澄清、管道选择、会话管理、讨论循环 | [roles/coordinator/role.md](roles/coordinator/role.md) |
+| `explorer` | EXPLORE-* | cli-explore-agent 多角度并行代码库探索 | [roles/explorer/role.md](roles/explorer/role.md) |
+| `analyst` | ANALYZE-* | CLI 多视角深度分析 | [roles/analyst/role.md](roles/analyst/role.md) |
+| `discussant` | DISCUSS-* | 用户反馈处理、方向调整、深入分析 | [roles/discussant/role.md](roles/discussant/role.md) |
+| `synthesizer` | SYNTH-* | 跨视角整合、结论生成、决策追踪 | [roles/synthesizer/role.md](roles/synthesizer/role.md) |
+
+## Shared Infrastructure
+
+### Role Isolation Rules
+
+**核心原则**: 每个角色仅能执行自己职责范围内的工作。
+
+#### Output Tagging（强制）
+
+所有角色的输出必须带 `[role_name]` 标识前缀：
+
+```javascript
+SendMessage({ content: `## [${role}] ...`, summary: `[${role}] ...` })
+mcp__ccw-tools__team_msg({ summary: `[${role}] ...` })
+```
+
+#### Coordinator 隔离
+
+| 允许 | 禁止 |
+|------|------|
+| 话题澄清 (AskUserQuestion) | ❌ 直接执行代码探索或分析 |
+| 创建任务链 (TaskCreate) | ❌ 直接调用 cli-explore-agent |
+| 管道选择 + 讨论循环驱动 | ❌ 直接调用 CLI 分析工具 |
+| 监控进度 (消息总线) | ❌ 绕过 worker 自行完成 |
+
+#### Worker 隔离
+
+| 允许 | 禁止 |
+|------|------|
+| 处理自己前缀的任务 | ❌ 处理其他角色前缀的任务 |
+| 读写 shared-memory.json (自己的字段) | ❌ 为其他角色创建任务 |
+| SendMessage 给 coordinator | ❌ 直接与其他 worker 通信 |
+
+### Team Configuration
+
+```javascript
+const TEAM_CONFIG = {
+  name: "ultra-analyze",
+  sessionDir: ".workflow/.team/UAN-{slug}-{date}/",
+  msgDir: ".workflow/.team-msg/ultra-analyze/",
+  sharedMemory: "shared-memory.json",
+  analysisDimensions: ["architecture", "implementation", "performance", "security", "concept", "comparison", "decision"],
+  maxDiscussionRounds: 5
+}
+```
+
+### Shared Memory（核心产物）
+
+```javascript
+// 各角色读取共享记忆
+const memoryPath = `${sessionFolder}/shared-memory.json`
+let sharedMemory = {}
+try { sharedMemory = JSON.parse(Read(memoryPath)) } catch {}
+
+// 各角色写入自己负责的字段：
+// explorer    → sharedMemory.explorations
+// analyst     → sharedMemory.analyses
+// discussant  → sharedMemory.discussions
+// synthesizer → sharedMemory.synthesis
+// coordinator → sharedMemory.decision_trail + current_understanding
+Write(memoryPath, JSON.stringify(sharedMemory, null, 2))
+```
+
+### Message Bus (All Roles)
+
+```javascript
+mcp__ccw-tools__team_msg({
+  operation: "log",
+  team: teamName,
+  from: role,
+  to: "coordinator",
+  type: "<type>",
+  summary: `[${role}] <summary>`,
+  ref: "<file_path>"
+})
+```
+
+| Role | Types |
+|------|-------|
+| coordinator | `pipeline_selected`, `discussion_round`, `direction_adjusted`, `task_unblocked`, `error`, `shutdown` |
+| explorer | `exploration_ready`, `error` |
+| analyst | `analysis_ready`, `error` |
+| discussant | `discussion_processed`, `error` |
+| synthesizer | `synthesis_ready`, `error` |
+
+### CLI 回退
+
+```javascript
+Bash(`ccw team log --team "${teamName}" --from "${role}" --to "coordinator" --type "<type>" --summary "<摘要>" --json`)
+```
+
+### Task Lifecycle (All Worker Roles)
+
+```javascript
+const tasks = TaskList()
+const myTasks = tasks.filter(t =>
+  t.subject.startsWith(`${VALID_ROLES[role].prefix}-`) &&
+  t.owner === role &&
+  t.status === 'pending' &&
+  t.blockedBy.length === 0
+)
+if (myTasks.length === 0) return
+const task = TaskGet({ taskId: myTasks[0].id })
+TaskUpdate({ taskId: task.id, status: 'in_progress' })
+
+// Phase 2-4: Role-specific
+// Phase 5: Report + Loop
+mcp__ccw-tools__team_msg({ operation: "log", team: teamName, from: role, to: "coordinator", type: "...", summary: `[${role}] ...` })
+SendMessage({ type: "message", recipient: "coordinator", content: `## [${role}] ...`, summary: `[${role}] ...` })
+TaskUpdate({ taskId: task.id, status: 'completed' })
+```
+
+## Three-Mode Pipeline Architecture
+
+```
+Quick:    EXPLORE-001 → ANALYZE-001 → SYNTH-001
+Standard: [EXPLORE-001..N](parallel) → [ANALYZE-001..N](parallel) → DISCUSS-001 → SYNTH-001
+Deep:     [EXPLORE-001..N] → [ANALYZE-001..N] → DISCUSS-001 → ANALYZE-fix → DISCUSS-002 → ... → SYNTH-001
+```
+
+### Mode Auto-Detection
+
+```javascript
+function detectPipelineMode(args, taskDescription) {
+  const modeMatch = args.match(/--mode[=\s]+(quick|standard|deep)/)
+  if (modeMatch) return modeMatch[1]
+  // 自动检测
+  if (/快速|quick|overview|概览/.test(taskDescription)) return 'quick'
+  if (/深入|deep|thorough|详细|全面/.test(taskDescription)) return 'deep'
+  return 'standard'
+}
+```
+
+### Discussion Loop (Deep Mode)
+
+```
+coordinator(AskUser) → DISCUSS-N(deepen) → [optional ANALYZE-fix] → coordinator(AskUser) → ... → SYNTH
+```
+
+## Decision Recording Protocol
+
+**⚠️ CRITICAL**: 继承自原 analyze-with-file 命令。分析过程中以下情况必须立即记录到 discussion.md：
+
+| Trigger | What to Record | Target Section |
+|---------|---------------|----------------|
+| **Direction choice** | 选择了什么、为什么、放弃了哪些替代方案 | `#### Decision Log` |
+| **Key finding** | 发现内容、影响范围、置信度 | `#### Key Findings` |
+| **Assumption change** | 旧假设→新理解、变更原因、影响 | `#### Corrected Assumptions` |
+| **User feedback** | 用户原始输入、采纳/调整理由 | `#### User Input` |
+

+## Error Handling
+
+| Scenario | Resolution |
+|----------|------------|
+| Unknown --role value | Error with available role list |
+| Missing --role arg | Error with usage hint |
+| Role file not found | Error with expected path (roles/{name}/role.md) |
+| Task prefix conflict | Log warning, proceed |
+| Discussion loop stuck >5 rounds | Force synthesis, offer continuation |
+| CLI tool unavailable | Fallback chain: gemini → codex → manual analysis |
+| Explorer agent fails | Continue with available context, note limitation |
