## What changed
- Add cloud archive and unarchive requests and support listing archived threads.
- Detach successfully archived threads and emit archive notifications. Report loaded cloud threads from live attachments rather than cached resume metadata, including after archive failures.
- Scope resume picker archive state and transcript previews by backend and thread so archiving a cloud session preserves a local session with the same ID.
- Limit cloud task archive cleanup to the selected thread, preserving child agents and their active session state, and update the confirmation text accordingly.
## Testing
Add regression coverage for archive acknowledgments, archived-thread discovery and restoration, attachment state after archive failures, same-ID sessions across backends, and preservation of attached child agents.

## What changed
- Register an additional Cloud connection on supported macOS and Linux launches when `TuiMultiBackend` is enabled, using the selected ChatGPT account and local network policy.
- Preserve backend settings and identify Cloud in connection controls and status.
- Let Cloud supply the model when a thread opens, skip local skills requests and stale results, and allow resume without a local working-directory override.
- Preserve Git metadata in Cloud thread snapshots and continue history hydration past empty filtered pages within the scan budget.
- Report Cloud connection failures and require reopening Codex to reconnect.
## Testing
Add regression coverage for Cloud model bootstrap, skipped skills requests, resume directory handling, history pagination through filtered pages, and Git metadata preservation.

## What changed
Add `Client::list_threads` with cursor pagination, page limits, sorting, and originator filtering for unarchived threads. Return thread snapshots, optional read states, and forward and backward cursors while preserving server order and duplicate entries.
Allow stored thread snapshots to contain empty session IDs and model providers while retaining nonempty requirements for activation. Preserve the original snapshot protobuf bytes.
## Testing
Add fixture tests for pagination requests, default query encoding, snapshot and read-state preservation, legacy empty metadata, invalid responses, and activation validation.
