v0.3.2

Adds three tab-lifecycle tools: close_tab, go_back, go_forward.

Added

• close_tab — close a tab this session has leased. Closing the last remaining tab
  in a window closes the window (expected, not a bug). The lease and any active
  start_console/start_network capture on the tab are cleared automatically.
• go_back / go_forward — navigate a leased tab through its browsing history, like
  the browser's own back/forward buttons. If the destination is on the blacklist, the
  same confirmation flow as navigate triggers; declining reverts the tab and returns
  blacklisted_denied.

Fixed (same batch, caught by final review before release)

• The initial go_back/go_forward implementation had no policy check at all, which
  could move a tab onto a blacklisted URL with zero confirmation. Fixed before this
  release shipped — see the design spec for detail.

Install

Grab the .xpi below, drag into a Firefox window (or about:addons → gear icon → "Install
Add-on From File..."). Same add-on ID as prior releases, so this upgrades an existing install
in place — no need to remove the old one first.
