cortex 0.99.1

• Cortex in bb for every provider. The bb plugin gives pi, Claude Code, Codex and every other provider the same
  cortex_update and cortex_recall tools, usage notes and memory summary. Inside bb the pi extension steps aside
  for the plugin; plain pi, and a pi -p run from a bb thread's shell, keep the extension as before.
• Recall and saving in bb. A thread's first request, or one that asks about earlier work, brings the matching
  tasks as a hidden message in pi, Claude Code and Codex threads. After a request that changed files and saved
  nothing, a thread that saves memory gets one hidden save turn, as in plain pi.
• Skills for Claude Code. The bb plugin carries the cortex skills and gives them to Claude Code threads, which do
  not read ~/.agents/skills.
