* fix(#3021): recognize worktree-wf_* branch namespace in all guards
The Claude-orchestration Workflow backend (#1143) creates per-plan
worktrees on branches named worktree-wf_<runid>-<n>. Four independent
copies of the agent branch allow-list regex (^(worktree-)?agent-...) never
learned this namespace:
- hooks/gsd-worktree-path-guard.js:176 — FAILED OPEN (process.exit(0)),
silently disabling path containment for exactly the concurrent dispatch
mode where cross-worktree writes are most likely
- src/worktree-safety.cts:21 — silently dropped cleanup-wave manifest
entries
- agents/gsd-executor.md:503 — FATAL halt on branch check
- gsd-core/references/worktree-branch-check.md:33 — same FATAL halt
Extended all four to ^((worktree-)?agent-|worktree-wf_)[A-Za-z0-9._/-]+$.
The path guard now correctly blocks cross-worktree writes for Workflow-
backend branches instead of no-op'ing.
