تحميل codeg 0.20.3

- feat(chat-channel): Telegram Topic mode. Run multiple sessions inside one Telegram forum supergroup, each bound to its own topic. /task <description> opens a new topic and session, /resume <id> binds an existing one, and plain text follows up in the current topic. Requires a forum supergroup with the bot as a topic-managing admin. Thanks @AnotiaWang (#322).
- feat(codex): Custom Codex models without hand-editing JSON. A structured editor in Codex settings lets you define custom models and curate the list — clone an official model, override only what differs, pick enum fields from dropdowns. Official models are read live from the launched Codex, so new ones appear automatically.
- feat(grok): Real Grok permission modes and reasoning effort. Permission mode now uses Grok's own --permission-mode values (old settings migrate automatically), and the reasoning-effort selector follows the chosen model — showing only the efforts it supports, or hiding entirely when it has none.
- feat(skills): Author your own skills. A new Custom tab in Skill Packs lets you create, edit, duplicate, and delete skills in the shared store and enable them for any agent — write once, reuse everywhere. Import from a local folder or from an agent's existing global skills.
- fix(chat): Async sub-agent results settle cleanly into their turn. Held-turn content no longer double-renders, the launch card updates in place to its finished result, and the "syncing results" strip stops lingering.
- fix(chat): Correct first-reply stats after resuming a conversation. The first reply after reopening a conversation no longer absorbs every earlier turn's duration and tokens — each reply reports only its own.
- fix(acp): A session's last error survives a reconnect. Reconnecting after missing the live error event still shows what went wrong, and a stale error is never resurrected onto a session that moved on. Thanks @ijry (#314).
- fix(chat-channel): Telegram tokens no longer leak; @username channels bind correctly. Bot tokens are scrubbed from error messages, and an @username is resolved to its numeric chat id so a follow-up no longer spawns a duplicate agent.
- fix(session): Completed sessions show their true runtime, computed from start and end timestamps. Thanks @cnYui (#311).
- fix(editor): Windows IME composition is preserved when typing Chinese, Japanese, or Korean in the built-in editor. Thanks @youxikexue (#332).
- fix(docker): Docker builds include the pnpm workspace config, so container and self-hosted deployments build cleanly. Thanks @AnotiaWang (#322).
- chore(agents): Bundled agents refreshed — Claude Code (0.59.0), OpenCode (1.17.20), OpenClaw (2026.7.1), Cline (3.0.40), CodeBuddy (2.121.2), Kimi Code (0.24.1), Grok (0.2.101).
