Moved ShowDiffModal/ShowWorktreeModal delegate wiring from
AgentStripView (child, possibly detached) to DetailsIslandView
(the VM's DataContext owner). TopLevel is resolved at invocation
time, not at wiring time, so attachment order no longer matters.
AgentStripView reduced to InitializeComponent() only.

Adds WorktreeModalView/ViewModel showing git status --porcelain as a
recursive file tree with M/A/D/? status badges. Wires the Worktree
button in AgentStripView to OpenWorktreeCommand on DetailsIslandViewModel.
Adds GetStatusPorcelainAsync to GitService.

Adds AgentStripView (status/model/turns/tokens row, worktree path,
branch line, action buttons), SessionTerminalView (scrollable log with
auto-scroll on CollectionChanged, prompt TextBox with Enter binding),
and replaces DetailsIslandView placeholder with full ScrollViewer layout
containing editable title, agent strip, terminal, subtasks, notes.
