Inspector shows "Disconnected" after system sleep with no reconnect option, unlike Network tab which has offline/reconnect support

Bắt đầu bằng cách tái hiện chuỗi ngủ và thức dậy trong một phiên debug Flutter, sau đó so sánh trạng thái ngắt kết nối của Inspector với hành vi offline và kết nối lại của tab Network. Truy tìm điểm bắt đầu đi vào trạng thái ngắt kết nối của Inspector và xác định cách phát hiện tính khả dụng của VM Service; công việc được xem là hoàn tất khi Inspector có thể kết nối lại hoặc cung cấp một thao tác reconnect hoặc refresh hoạt động mà không cần khởi động lại ứng dụng.

Description

When the host machine goes to sleep while a Flutter debug session is running,
the DevTools Inspector panel becomes permanently disconnected and shows
"Run a new debug session to reconnect." — requiring a full app restart.

In contrast, the Network tab handles this gracefully:

• Shows the same "Disconnected" state
• Offers a "Review recent data (offline)" button
• Reconnects automatically or with a simple tab close/reopen

Steps to Reproduce

1. Start a Flutter debug session
2. Open DevTools → Inspector
3. Let the machine go to sleep (or manually suspend)
4. Wake the machine
5. Observe Inspector is stuck in "Disconnected" state

Expected Behavior

Inspector should either:

• Option A: Auto-reconnect when the VM Service becomes available again
• Option B: Show a "Reconnect" or "Refresh" button (similar to how
  Network tab handles disconnection)

Actual Behavior

Inspector shows "Disconnected - Run a new debug session to reconnect."
No reconnect/refresh option is available. A full app restart is required.

Workaround

For Network tab: close and reopen the tab in DevTools → reconnects fine
For Inspector: must stop and re-run the entire debug session

Proposal

Add a Reconnect / Refresh button to the Inspector's disconnected state,
consistent with the Network tab's offline handling UX.
