[Bug]: container stats does not restore terminal upon exit

[mislav]

I have done the following

• I have searched the existing issues
• If possible, I've reproduced the issue using the 'main' branch of this project

Steps to reproduce

1. Start container stats (streaming mode)
2. Ctrl-C to exit

Current behavior

After container stats exits, the terminal is still in "alternate" terminal screen state. (I've confirmed this using Ghostty Terminal Inspector feature.) The visible result of this in my terminal emulator is that the mouse scroll feature no longer works to navigate terminal scrollback.

In macOS Terminal.app, the mouse scroll feature does not seem affected, but you can verify that you are still in "alternate" screen by inspecting the "View" menu: “Show alternate screen” will be grayed out.

Expected behavior

Upon exiting, even as a result of Ctrl-C, container stats should restore terminal properties to their original values, i.e. switch to the "primary" screen, restore cursor visibility, and restore mouse features.

My suspicion is that the container process exits before the defer block had a chance to run:

container/Sources/ContainerCommands/Container/ContainerStats.swift

Lines 49 to 60 in 31c866a

	// Streaming mode - continuously update like top
	// Enter alternate screen buffer and hide cursor
	print("\u{001B}[?1049h\u{001B}[?25l", terminator: "")
	fflush(stdout)
	defer {
	// Exit alternate screen buffer and show cursor again
	print("\u{001B}[?25h\u{001B}[?1049l", terminator: "")
	fflush(stdout)
	}
	try await runStreaming()

Environment

- OS: 26.2
- Xcode: 26.4
- Container: 0.10.0
