[Bug]: Usage page loads forever when a remembered remote environment is offline

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/web

Steps to reproduce

1. Configure T3 Code with two desktop environments/devices.
2. Leave both environments remembered by the client.
3. Put one device to sleep (or otherwise make its remote environment unreachable).
4. On the online device, open Usage.
5. Wait beyond the remote connection timeout.

Expected behavior

The Usage page should eventually show totals from the available environment and clearly mark the offline environment as unavailable/incomplete. A disconnected device should reach a terminal error state or be excluded after a bounded timeout.

Actual behavior

The page remains on its loading skeleton indefinitely with “1 device still scanning.” The online environment completes successfully, while the offline environment is reconnecting and reports a 10-second remote endpoint timeout under Settings → Connections.

The remote usage request appears to remain pending instead of becoming a failure. In the current client flow, useUsage() treats an environment with no summary and no error as still reporting, and UsagePage deliberately holds all content while isPending || isPartial. Because the unreachable environment never becomes terminal, the page never displays even the completed device's totals.

Impact

Major degradation or frequent failure

Version or commit

0.0.34-nightly.20260810.1061

Environment

macOS desktop app; two remembered Mac environments connected using Tailscale HTTPS; one remote Mac asleep/unreachable.

Logs or stack traces

Remote environment endpoint https://<redacted-tailnet-host>/.well-known/t3/environment timed out after 10000ms.

The Connections screen continues showing “Failed to connect. Reconnecting...” / “Connecting...” while Usage remains on “1 device still scanning.”

Workaround

Wake the remote Mac so it reconnects, or temporarily remove the offline environment under Settings → Connections → Remote environments.
