What's New

Adds Claude Opus 5.5, GPT-6 models, and optional mosh support for remote sessions.

New Features

Add optional mosh support for interactive remote attaches to survive sleep and network changes.
Add Claude Opus 5.5 and GPT-6 variants to model pickers and launch commands.
Honor default model setting for Claude sessions instead of dropping it silently.

Improvements

Add SSH ControlMaster channel retry for large session fleets.
Improve web sidebar nesting to sync with TUI group and session structure.

Bug Fixes

Fix silent failure when moving sessions from the Edit dialog.
Fix background status polling during session moves.
Fix web sidebar nesting to match TUI order.

Upgrade Notes

To use the new mosh feature, install `mosh` locally and `mosh-server` on the remote, then set `transport = "mosh"` in your remote config. Ensure UDP ports 60000-61000 are allowed through firewalls or Tailscale. Codex sessions now accept `--effort max` and `--effort ultra` flags.
