feat: final 3 audit fixes — start gate, auto-PR, pre-launch

1. flowctl start: HARD REJECT parallel tasks without --force
   Previously: warning only (ignored 5 rounds). Now: error_exit.
   --force confirms worktree isolation will be used.

2. flowctl epic completion ship: auto gh pr create --draft
   Creates draft PR on feature branches. Graceful: gh missing → skip,
   on main → skip, PR exists → skip. URL included in JSON output.

3. flowctl pre-launch: 6-dimension ship-readiness check
   - code_quality: file count info
   - security: grep secrets in changed files (pass/fail)
   - accessibility: detect frontend changes (pass/warn)
   - infrastructure: detect .env/docker changes (pass/warn)
   - documentation: flag missing docs for significant changes (pass/warn)
   - performance: advisory info
   Exits 1 if any dimension fails. JSON output with ship_ready boolean.

381 tests pass.

+# 剩余 3 个问题解决方案
+
+> 基于 5 轮审计 + Claude Code hook 机制分析 | 2026-04-09
+
+---
+
+## 1. Worker Worktree 隔离 — PreToolUse Hook 拦截
+
+### 方案
+
+在 `hooks/hooks.json` 的 `PreToolUse` 中加一个 matcher `"Agent"`，hook 脚本检查：
+1. 读取 `$TOOL_INPUT` 环境变量（Claude Code 传给 hook 的 JSON）
+2. 检查是否有 `isolation: "worktree"` 参数
+3. 如果没有，检查是否有多个 in_progress 任务
+4. 如果有并行任务但没有 worktree → hook 返回非零退出码 → Claude Code 阻止调用
+
+```json
+{
+  "matcher": "Agent",
+  "hooks": [
+    {
+      "type": "command",
+      "command": "F=\"${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-}}/bin/flowctl\"; [ -x \"$F\" ] && \"$F\" hook check-worktree || true",
+      "timeout": 5
+    }
+  ],
+  "description": "Block Agent spawn without worktree isolation when parallel tasks exist"
+}
+```
+
+`flowctl hook check-worktree` 实现：
+```rust
+pub fn cmd_check_worktree() {
+    // 1. Read TOOL_INPUT env var
+    let input = std::env::var("TOOL_INPUT").unwrap_or_default();
+    
+    // 2. Check if isolation: "worktree" is present
+    if input.contains("\"isolation\"") && input.contains("\"worktree\"") {
+        std::process::exit(0); // OK — has worktree
+    }
+    
+    // 3. Check if there are parallel in_progress tasks
+    let flow_dir = get_flow_dir();
+    // ... count in_progress tasks ...
+    
+    if in_progress_count > 1 {
+        eprintln!("⚠️ BLOCKED: Agent spawn without isolation:\"worktree\" while {} tasks in_progress.", in_progress_count);
+        eprintln!("Add isolation: \"worktree\" to the Agent call to prevent race conditions.");
+        std::process::exit(2); // Non-zero → Claude Code blocks the tool call
+    }
+    
+    std::process::exit(0); // Single task or no parallel — OK
+}
+```
+
+### 不确定性
+
+Claude Code 的 `PreToolUse` hook 是否对 `Agent` 工具也触发？matcher 文档说支持工具名匹配，但 Agent 可能是内部工具。
+需要测试：在 hooks.json 加一个 `"matcher": "Agent"` 的 PreToolUse hook，看是否触发。
+
+### 备选方案（如果 hook 不对 Agent 触发）
+
+改为在 `flowctl start` 时**硬拒绝**第二个并行任务，除非传 `--worktree-confirmed`：
+```bash
+flowctl start fn-1.2 --worktree-confirmed --json
+```
+不传 → 拒绝。这样 AI 必须在 start 之前确认 worktree。
+
+---
+
+## 2. Create Draft PR — flowctl epic completion 内置
+
+### 方案
+
+让 `flowctl epic completion` 自动运行 `gh pr create`：
+
+```rust
+// 在 epic completion ship 执行时：
+fn auto_create_pr(epic_id: &str) {
+    // 1. 检查是否在 feature branch（不是 main/master）
+    let branch = Command::new("git").args(["branch", "--show-current"]).output();
+    if branch == "main" || branch == "master" { return; } // 直接 push 到 main 不需要 PR
+    
+    // 2. Push branch
+    Command::new("git").args(["push", "origin", "HEAD"]).status();
+    
+    // 3. Create draft PR
+    let title = format!("feat: {}", epic_title);
+    let body = format!("## Epic: {}\n\n{}", epic_id, epic_spec_summary);
+    Command::new("gh").args([
+        "pr", "create",
+        "--title", &title,
+        "--body", &body,
+        "--draft"
+    ]).status();
+}
+```
+
+### 实现细节
+
+- 只在 feature branch 上创建 PR（main/master 上不创建）
+- `--no-pr` 标志跳过
+- `gh` CLI 不可用时静默跳过（check `which gh`）
+- PR body 包含 epic spec 摘要
+
+---
+
+## 3. Pre-launch 6 维度 — flowctl pre-launch 命令
+
+### 方案
+
+新增 `flowctl pre-launch --epic <id> --json` 命令，自动检查能自动化的维度：
+
+```rust
+pub fn cmd_pre_launch(epic_id: &str) -> PreLaunchResult {
+    let mut checks = Vec::new();
+    let changed_files = get_changed_files(); // git diff --name-only main...HEAD
+    
+    // 1. Code quality: guard 已跑过（检查 .state/ 标记）
+    checks.push(check_guard_passed());
+    
+    // 2. Security: grep secrets in changed files
+    let secrets = Command::new("grep")
+        .args(["-rn", "password\\|secret\\|api_key\\|token\\|private_key"])
+        .args(&changed_files)
+        .output();
+    checks.push(Check {
+        name: "security",
+        passed: secrets.stdout.is_empty(),
+        detail: if secrets.stdout.is_empty() { "clean" } else { "SECRETS FOUND" },
+    });
+    
+    // 3. Performance: check for N+1 patterns (简单启发)
+    // 4. Accessibility: check if frontend files changed, if so flag for manual review
+    let has_frontend = changed_files.iter().any(|f| 
+        f.ends_with(".tsx") || f.ends_with(".jsx") || f.ends_with(".vue") || f.ends_with(".svelte")
+    );
+    checks.push(Check {
+        name: "accessibility",
+        passed: !has_frontend, // If frontend changed, needs manual check
+        detail: if has_frontend { "frontend changed — verify a11y" } else { "no frontend changes" },
+    });
+    
+    // 5. Infrastructure: check .env.example or env docs
+    // 6. Documentation: check if README/CHANGELOG modified
+    let has_doc_update = changed_files.iter().any(|f| 
+        f.contains("README") || f.contains("CHANGELOG")
+    );
+    
+    PreLaunchResult { checks, all_passed: checks.iter().all(|c| c.passed) }
+}
+```
+
+然后在 `flowctl phase done --phase close` 门禁中加 `--pre-launch-ran` 标志（和 `--guard-ran` 一样）。
+
+---
+
+## 实施优先级
+
+| # | 方案 | 代码量 | 效果 |
+|---|------|--------|------|
+| 1 | `flowctl pre-launch` 命令 + close 门禁 | ~200 行 Rust | 自动化 6 维度中 4 个 |
+| 2 | `epic completion` 自动 PR | ~50 行 Rust | 解决 4 轮未创建 PR |
+| 3 | PreToolUse hook 拦截 Agent | ~80 行 Rust + hooks.json | 解决 worktree（需验证 hook 是否对 Agent 触发） |
