my last session i lost all my changes can you redo them? The healthcheck in `diagnostics.txt` is green: `"ok": true`, auth OK, bundled Copilot CLI OK, git OK, gh CLI OK, database OK.

The actual errors near the end are all around one repeated cloud workspace diff RPC for `aabiro/video-time-travel`:

- [github-app.12093.log](/Users/aaryn/.copilot/logs/github-app.12093.log:224): `session.workspaces.diff` first fails with `Failed to submit RPC request`.
- [github-app.12093.log](/Users/aaryn/.copilot/logs/github-app.12093.log:274): frontend error: `Failed to list workspace file paths... Cloud workspaces do not have a local workspace path.`
- [github-app.12093.log](/Users/aaryn/.copilot/logs/github-app.12093.log:280): repeated `RPC response timeout after 30000ms`.
- Same 30s timeout repeats at lines `286`, `292`, `296`, and finally [line 343](/Users/aaryn/.copilot/logs/github-app.12093.log:343).

The call that keeps hanging is:

`session.workspaces.diff`

for workspace:

`26f5d746-c207-42de-8e64-c8142f633cdd`

session:

`b2580cad-c9aa-456e-b202-940f23c53681`

After the last timeout at `18:29:13Z`, the app keeps reporting session liveness as `responsive`, so the app process is not dead. The stuck part is specifically fetching/subscribing to workspace changes for that cloud workspace diff.

Start with diagnostics.txt and the referenced github-app.12093.log entries around lines 224-343, then reproduce the reported `copilot --remote --resume` command. Trace the repeated `session.workspaces.diff` timeout for the listed workspace and session; done means the lost changes can be recovered or the failure is clearly diagnosed and the resume flow behaves correctly.
