Lamp 0.13.0

• Building with your Claude or ChatGPT subscription no longer needs their apps or a command-line install:
  choose the agent and Lamp fetches its own copy, checked against the maker's signature, and keeps it up to
  date. A Claude Code or Codex already on your Mac is used as it is, with its sign-in.
• The welcome asks what you wish your Mac did, and a wish written on lamp.dev arrives in Lamp without
  pasting. The starter ideas are real situations instead of app categories.
• Duplicate an app to try a variation: the copy has the same code, history and icon on a new colour,
  with an empty chat and its own data.
• Your apps appear in Finder's Applications folder, and they open the files they're for: drop a file on an
  app's icon, or choose it under Open With.
• When an app uses your other apps, you can watch it happen: a glow follows the window in use and a cursor
  shows each step, with approval beside the action and a Stop button. It's on by default with a Claude Code
  or ChatGPT sign-in or an OpenRouter key.
• Permission screens have one place to drag the app from, and Open System Settings always brings the
  panel back.
• The build card no longer says Ready over an app that couldn't be installed or opened.
