codeg 0.15.1 allalaadimine

- feat(backup): Export a portable backup of your codeg data and restore from it later. Backups can be passphrase-encrypted, optionally bundle your agent CLI transcripts (Claude, Codex, Gemini, …), and restoring previews the archive and checks version compatibility before doing anything. Your current data is snapshotted first, so a restore can be rolled back if needed.
- feat(file-preview): Added a sandboxed HTML file preview that renders documents safely with scripts disabled, and the preview header now shows the HTML document's title.
- feat(sync): Open conversation tabs and the focused tab now stay in sync across your desktop and browser clients.
- feat(chat): The most recent reply's delegated sub-agents now surface in a top-right overlay, so you can follow delegated work at a glance.
- feat(web): Losing the WebSocket connection now recovers in place through a reconnect dialog, instead of forcing you to log in again.
- feat(chat): Markdown links and file paths in chat now show a type icon in front of them for quicker scanning.
- perf(sidebar): The conversation list is now virtualized for smooth scrolling and rendering even with a large number of conversations; a status change re-renders only the affected card, and sticky folder headers return as a floating overlay.
- fix(chat): Pasting an image from the clipboard now works on Linux and inside the Tauri webview.
- fix(sync): Viewing a shared conversation mid-turn no longer shows a duplicated in-flight prompt or reply.
- chore(registry): Bundled agents updated — Claude Code 0.42.0, OpenCode 1.16.2, Gemini CLI 0.45.2, and OpenClaw 2026.6.1.
