Ladda ner codeg 0.22.1

- feat(settings): A rebuilt Kimi Code panel with honest status. It reads config.toml back and shows the provider, model and context window really on disk, instead of turning green whenever a token was seeded. Required fields are validated before saving — including "Max context size", which Kimi needs or it discards the whole model block and every prompt comes back empty.
- feat(git-log): Follow the branch you're on in the Commits tab. A HEAD row keeps the history on your current branch across checkouts made anywhere, works while detached, and reports push status against the branch HEAD actually resolves to.
- feat(sidebar): Import local sessions without hunting for the button. The empty sidebar offers it directly, and it's in the right-click menu on the blank area of the list.
- perf(acp): Custom-agent conversations open far faster. Streamed fragments are merged as they're written: a 100-turn conversation goes from 9.3 MB and 78 ms to read, to 0.7 MB and under a millisecond. Existing transcripts read exactly the same.
- fix(chat): Images and files sent from Windows work again. Pasting an image in a web or remote workspace failed with os error 123, and attachments arrived as links the agent couldn't open. Fixed on both sides, so mismatched client and server versions still work (#392).
- fix(acp): Running a script the agent just wrote no longer fails. A "Text file busy" refusal on Linux is now retried briefly instead of surfaced as an error.
