Intended vs Implemented has moved

intended-vs-implemented is maintained in phuryn/product-engineering, in its ai-shipping plugin, with the rest of the AI Shipping Kit. This skill stays in pm-skills only so an agent that loads it knows where it went.

• ai-shipping:intended-vs-implemented is installed: use it, not this copy.

• It isn't: tell the user that intended-vs-implemented moved and how to install it, then help with the task as you would without it:

  claude plugin marketplace add phuryn/product-engineering
  claude plugin install ai-shipping@product-engineering
  

  Other agents: the repository's README. Once it's installed, turn off pm-ai-shipping here, so this copy no longer loads beside it.
