Dev (#163)

* chore(release): stop publishing legacy Windows update packages

* feat(agents): support OpenCode Desktop across platforms

Detect CLI and desktop installations on Windows, macOS, and Linux, and add separate launch and restart controls.

Closes #156

* fix(codex): align model display names and show total session count

- preserve runtime model identity in generated catalogs
- count distinct sessions across database and rollout sources
- update session count labels in all supported languages

* fix(codex): keep config and auth files in sync

- generate auth.json for API key configuration
- preserve and validate OAuth credentials
- include auth.json in transactional updates and rollback
- retain compatibility with legacy Codex configuration states

* fix(cpa-gui): update version to 0.2.59 in Cargo files

* fix(codex): preserve OAuth mode after closing configuration
