.SYNOPSIS
  Копирует Cursor rules из локального $HOME\CursorRules в текущий проект.

.DESCRIPTION
  Источник — локальный клон репозитория Rules ($HOME\CursorRules), не remote напрямую.
  На новом ПК сначала: bootstrap.ps1 / bootstrap.sh (SSH + clone Rules).
  Обновить правила из remote: init-cursor -Update

.EXAMPLE
  cd C:\Users\papat\Projects\MyRepo
  init-cursor
  init-cursor -Update
#>
