0.21.1

• Track Worktree 0.11.0 (from 0.10.0). verified.json and the eval workflow move to 0.11.0 after
  agentplugins-check tools (42 spelled commands) and the worktree-onboarding trial, whose
  baseline is the run of 2026-10-07 (11 → 9 tool calls). worktree skill without --out now
  prints the skill and writes no file; no skill here runs it, because the plugin ships
  worktree:managing-worktrees.
• worktree:managing-worktrees step 1 no longer reads as an instruction to publish every commit.
  When a task stops at a local commit, the tree is archived or handed off, never published to make
  it removable. The trial quoted the old sentence as conflicting with a commit-only request.
