Wire TasksIslandViewModel to TaskUpdated/WorktreeUpdated/TaskMessage worker
events so rows refresh without a full reload; add ForegroundHelper to permit
wt.exe to take foreground on planning launch; misc UI polish on lists, task
rows and settings modal.

Both modals now use SystemDecorations=None with a draggable title bar,
sectioned layout matching the rest of the island shell, Escape-to-cancel,
and themed brushes instead of hard-coded colours. ListSettings adds a
Browse... button that reads agent frontmatter from arbitrary .md files.
- Count additions/deletions per file as lines are parsed.
- Surface load failures and empty-diff states via StatusMessage.
- Pass the worktree base commit so diffs render against the branch
base, not just the working-tree HEAD.
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.
