v2.3.0 — Remove GOAL mode

Removed

• Built-in goal-md skill and harness/goal/ scaffold
• Dual-path workflow (regular vs GOAL); single todo + AC path only

Notes

• Existing repos with harness/goal/ are unaffected until update; the directory is no longer created on fresh install
• Run harness/scripts/mini_harness.py update to drop managed goal-md skill copy

---

移除

• 内置 goal-md Skill 与 harness/goal/ 脚手架
• 双路径工作流（常规 vs GOAL）；恢复单一 todo + AC 流程

说明

• 已有 harness/goal/ 的仓库在 update 前不受影响；新 install 不再创建该目录
• 执行 harness/scripts/mini_harness.py update 可移除受管副本中的 goal-md
