[严重] 隔离目标脚本并修复输入注入
- 目标仓的
run-suite.sh会继承攻击步骤中的LLM_API_KEY。执行目标脚本时请使用最小化环境，或仅允许受信仓库作为target_repo。 target_repo在.github/workflows/adversary.yml:115直接内插到 shell。引号等元字符可注入命令。请改为通过env传入并引用变量。

统一两种事件的目标路径重定位，并先验证原始路径。
当前重定位逻辑只位于 workflow_dispatch 分支。repository_dispatch 即使完成了 external-target/ checkout，也会保留未加前缀的 ADV_SPEC_PATH，导致预检读取源仓同名路径或直接失败。
此外，/foo 会先变为 external-target//foo，从而绕过后续的绝对路径检查。请先验证原始 t 为相对路径且不含 ..，再在两种事件分支统一添加 external-target/ 前缀。

禁止将 target_repo 直接插入 shell。
inputs.target_repo 和 github.event.client_payload.target_repo 可控。当前表达式会先注入 run 脚本，再由 Bash 解析。带引号或换行的值可以结束 XT_REPO 字符串并执行额外命令。可触发该 workflow 的调用者可以篡改工作区并影响后续步骤。
请在 step 的 env 中定义 ADV_TARGET_REPO，然后只使用 [[ -n "$ADV_TARGET_REPO" ]]。不要在 run 中保留 ${{ ... }}。
依据路径指令：非受控输入禁止使用 ${{ }} 直接内插 shell，必须经 env 中转。

变更
adversary.yml 增 target_repo/target_ref 入参（workflow_dispatch + repository_dispatch 载荷）：被审 spec 在异仓时（PM 优先范式常态——spec 落治理仓 .github），自仓 checkout 继续供 pipeline/adversary 审判脚本与 metering 账本，目标仓 checkout 至 external-target/ 并重定位目标目录前缀；路径安全校验（相对+无..）语义不变。
