Patch Changes

• 8fee5f7: Identify a tab's engine from its process tree instead of its window title

  A shell tab where you ran claude yourself was identified by matching the OSC
  window title against each engine's name. Engine titles are free-form activity
  text, so a claude session whose summary mentioned "codex" relabelled its tab
  codex and attached a Codex turn detector. Identity now comes from walking the
  tab's shell for a live engine process, which also sees through launcher
  wrappers and aliases, and is released the moment that process exits.
