feat: stale worktrees

[felipe-software]

Add stale worktree detection, busy branch indicators, and a docked terminal panel to the sidebar

• Introduces a stale-worktree status in the sidebar via a new sidebar-item-status.ts module that centralizes icon/pill/label computation for all branch states.
• Branch rows in the sidebar now show busy spinners, hide the age pill when an action is active, and support creating a worktree via a new checkout button when none exists.
• Busy projects are promoted to the top of their group and trigger branch loading even when collapsed, showing a preview of their busy branches.
• Adds a bottom-docked, pointer-resizable GlobalTerminalPanel and StatusBar to the app shell, displaying aggregate counts (stale worktrees, busy terminals, PRs, worktrees, branches) and allowing terminal selection.
• Introduces getBusyTerminalSummary in the terminal store and useAppStatusSummary hook to propagate busy terminal and branch metrics throughout the component tree.
• Behavioral Change: MainPanel and BranchEmptyState switch from h-dvh to h-full to fit the new bottom-docked layout.

🟢 Low sidebar/sidebar-branch-item.tsx:134

The button that creates a worktree uses text-danger-foreground, so it renders with the same danger color as the remove button. Creating a worktree is not a destructive operation, so the button incorrectly signals danger to the user. Change the text color to a neutral class such as text-muted-foreground so that only destructive actions use danger styling.

Suggested change

	data-[hover=true]:bg-sidebar-accent
	className="text-muted-foreground
