UR-Nexus 1.65.9

• Fixed the plan-file/task-list deadlock. While plan mode is active, the exact
  normalized session plan file can be written before actionable tasks exist;
  ordinary workspace mutations still require TaskCreate/TodoWrite, and
  permission or hook rewrites are reclassified at the final execution boundary.
• Fixed ExitPlanMode approval races. Permission approval can change the mode
  and rewrite allowed prompts or edited plan content without causing a false
  “not in plan mode” error, while genuinely new out-of-mode calls remain
  rejected. The compact execution contract now distinguishes ordered task
  tracking from explicit plan mode for weaker models.
• Fixed Linux GitHub Actions and release validation without misrepresenting the
  product surface. Registry checks now use the platform-neutral
  167-command/160-visible/235-token baseline and verify the supported macOS and
  x64 Windows /desktop (/app) delta separately.
