codeg 0.22.0 allalaadimine

- feat(acp): Add any ACP agent to codeg, and use it like a built-in one. Browse the agent registry in Agent settings and install with a click, or add your own by hand with its icon — codeg picks the package that fits your machine and says up front when an agent doesn't support your platform. Once added, it appears in the agent picker and everywhere else an agent is named, its conversations are recorded, listed and searchable, and it takes @ delegation and skills — expert, Office and science packs included. Edit or remove it any time from its settings card.
- feat(agents): An agent you installed yourself is now recognized. If the agent's command is already on your system, codeg finds it and shows its real version instead of leaving it marked "not installed".
- feat(tabs): Split the conversation view into as many panes as you like. Right-click a tab to split right or down, drag the dividers to resize, and drag tabs from one pane to another. Each pane keeps its own tabs and its own new-conversation button, your layout is remembered, and a conversation that's mid-reply keeps running while you rearrange.
- feat(tabs): Unsent drafts come back after a restart. A draft tab returns to the pane you left it in, with the text you had typed still in the box.
- feat(claude): Watch Claude's sub-agents work in real time. A sub-agent's output now streams inside its card as it works, instead of appearing all at once when it finishes. Tool cards and permission prompts also lead with a plain description of what the command does.
- feat(update): New versions announce themselves in the status bar. A badge appears with the version, the release notes and the update button. Dismiss it and it stays quiet in every window until the next release.
- feat(chat): Right-click a file mentioned in a conversation. Reveal it in Finder / Explorer, copy its relative path, or copy its full path — the same actions the file tree offers.
- feat(delegation): Mention a session with @ and the agent will go read it.
- fix(chat): Images sent from the web or a remote workspace no longer disappear. Two screenshots used to be enough for a message to fail silently. Images now upload as you attach them, the limit per image goes from 2 MB to 20 MB, and a failed send tells you and hands your message back.
- fix(composer): Codex skills run properly, and pasted text keeps its references. Picking a Codex skill now sends the form Codex actually understands, and pasting text containing file links or commands turns them back into the badges you'd see in a sent message.
- fix(chat): A link before a Chinese full stop no longer swallows the bracket. (https://xxx.com/o/r)。 now links the address only.
- fix(kimi): Kimi's questions show the answer you picked instead of "no selection" — in existing conversations too, as soon as you reopen them.
- docs(readme): A leaner README, with the full manual at docs.codeg.app. It opens on a workspace screenshot, introduces the iOS and Android apps, and corrects the server install steps.
- chore(acp): Updated the built-in agents. Claude Code 0.63.0, OpenCode 1.18.8, CodeBuddy 2.128.0 and Kimi Code 0.29.2.
