v2.1.0

Changed

• Use the same short command set for plans and goals: status, resume,
  pause, cancel, hide, and help. Advanced recovery flags and
  compatibility commands remain available through /exec help advanced.
• Cancelled runs disappear from the strip and footer immediately, including
  after reload, branch navigation, and new sessions. No separate clear or
  cleanup command is needed. Existing cancelled records are hidden too.
• /goal stop now means final cancellation, matching /exec stop.
  stop remains a compatibility name for cancel in both commands.
• hide toggles progress display without changing execution. Goals also
  accept the compatibility display controls ui on|off, show, and clear.

Fixed

• Share the lease, mutation, and recovery gates for goal and plan controls.
  Implicit goal controls select eligible work in the current project instead
  of a newer finished or unrelated goal.
• Prevent resume and optional review waivers from restarting a finally
  cancelled run whose worker retirement failed.

Upgrade

• After upgrading, restart Pi sessions sharing the registry. Saved work,
  branches, worktrees, and worker ownership evidence are preserved.
• Change scripts that used /goal stop for resumable pauses to
  /goal pause. Otherwise, stop now ends the goal finally.
• Use ui off for repeated idempotent hiding in scripts.
  Repeating hide now restores the display.
• Cancellation is not successful completion or proof of worker exit. Shutdown
  tracking continues safely in the background; unresolved ownership stays
  reserved.
