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

## 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.

Start by reproducing the sleep-and-wake sequence with a Flutter debug session, then compare the Inspector disconnected state with the Network tab's offline and reconnect behavior. Trace the Inspector's disconnected-state entry point and determine how VM Service availability is detected; done means the Inspector can reconnect or offers a working reconnect or refresh action without restarting the app.
