落地任务复用治理规则与 worktree 对齐检查 [09-09-trellis-workflow-alignment]

2026-09-09 本地已验证完成、待交审的治理修复，一直未提交：

- 6 个 skill（trellis-before-dev/brainstorm/check/continue/finish-work/start）
  统一改为"先检查当前和直接相关既有任务，复用优先于新建"，取代原来"复杂任务
  先请求新建 task"的默认动作；新增 worktree/active-task 一致性校验步骤。
- project-governance.md 新增两节：Task Reuse（任务复用判据）、Active Task And
  Worktree Alignment（激活任务与实际执行 worktree 一致性检查，防止跨 worktree
  会话把上一个任务的 workflow-state 当成当前任务）。
- workflow.md 的 Request Triage / Parent-Child 章节、no_task 面包屑同步改写。

本地已过 task validate、check-trellis-governance.mjs、check-process-contract.mjs、
audit-docs.mjs、git diff --check；无业务代码改动。

 # Task-Scoped Quality Check
 
+Verify the active task and actual validation worktree match the task/diff being checked; run official `task.py current --source` again if scope or cwd changed. Checks from the main checkout do not validate an edited isolated copy.

 1. Identify files changed by this task. Git dirty state is evidence, not permission to include other work.
 2. Read acceptance criteria and applicable quality contracts not already loaded. Check the complete task diff, not only the last chunk.
 3. Run the minimum meaningful checks: targeted regressions for behavior changes, relevant syntax/type/build checks for affected layers, and governance/reference checks for rules. Expand for shared contracts and cross-layer risks.
