AgentBar 1.2.1 — stale approval-state fix

1.2.1 - 2026-07-23

Fixed

• Sessions no longer get stuck on "needs approval": the legacy Notification hook
  could land late (including after the upstream dialog-flash race) and overwrite
  newer state with a stale permission flag. Permission state is now written solely
  by permission.js; the Notification hook is no longer installed and old
  registrations are cleaned up on next launch.
• The permission-dot icon now adapts to the menu bar appearance in System mode
  instead of rendering a hard-black glyph.
