v0.3.2

Added

• Three named permission modes: Manual (asks first), Plan (read-only
  planner) and Auto (skips prompts; system level commands stay blocked).
  Shift+Tab cycles Manual → Plan → Auto, and the status bar always shows the
  current mode. Auto replaces the old YOLO name; --auto joins --yolo, and
  the plan hand-off's "Code in Auto" button also answers to a.

Changed

• The tab bar now shows as soon as a session is open, so its + button is
  there to start a second session.
• Auto turned on with Ctrl+Y no longer gets carried into plan mode; Shift+Tab
  from Auto always goes back to Manual.
