Ներբեռնել codeg 0.14.12

- feat(server): Server and Docker deployments can now upgrade themselves in-place — no manual file replacement needed. The supervisor automatically validates the new version and rolls back if the trial run fails.
- feat(server): A manual rollback action is now available in Server Update settings, letting you revert to the previous version at any time.
- feat(delegation): Sub-agent sessions now open in a centered dialog, making it easier to follow a delegated task's progress alongside your main conversation.
- feat(delegation): Batch-polling delegation status is now supported — query multiple task IDs in a single call for lower overhead in multi-agent workflows.
- feat(tabs): Press Ctrl+Tab / Ctrl+Shift+Tab to cycle forward and backward through open conversation tabs — thanks to @mvanhorn (#246).
- fix(server): The access token no longer regenerates on restart, so existing clients stay connected after a server reboot.
- fix(delegation): Token usage is now correctly backfilled on the child sub-session reply, so cost tracking stays accurate.
- fix(model-provider): API keys containing non-ASCII characters no longer cause a panic when the key is masked for display.
- fix(update): The server upgrade process is now crash-safe: the web bundle swaps atomically, disk writes are verified, and a bad upgrade is self-healed on the next boot.
- fix(plan): The plan overlay now expands correctly, and stale plans are no longer shown where they should be hidden.
- chore(registry): Bundled Claude Code updated to 0.41.0 and Gemini CLI to 0.45.0.
