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。

+Before closeout, match the active task to the actual execution worktree and record phase, verification, remaining acceptance and who/what is pending. Follow project-governance.md → Active Task And Worktree Alignment. Official `task.py finish` only clears the session pointer; it is not task completion or archive. Do not silently switch to another business task or treat isolated-worktree notes as integrated changes.

 1. Compare this task with its acceptance criteria and latest validation evidence. Do not scan unrelated active tasks for cleanup.
 2. Report implementation, tests, independent review and deployment separately. A completed stage can leave the overall task active; unresolved acceptance must not be checked off.
 3. Update existing task notes with concise, redacted results and remaining steps. Record a journal only when useful or requested; avoid duplicating stable facts across documents.
