Pobierz codeg 0.21.2

- feat(git-log): The Commit history tab is now a continuous timeline. History renders as one virtualized timeline that loads older commits on demand as you scroll, so the whole log stays reachable — not just the first page.
- feat(file-tree): Drive the file tree from the keyboard. Arrow keys move, expand, and collapse the selection, Enter or Space opens a file or toggles a folder, and Home/End jump to the ends — with the selected row kept in view.
- feat(grok): Choose how Grok authenticates. Pick an official subscription (grok login), an XAI_API_KEY, or a custom endpoint; the panel shows only the credential that method needs and recognizes your current one from the saved config.
- feat(workspace): Frosted surfaces over a background image. With a background image enabled, inline code, message bubbles, delegation cards, and Monaco's sticky-scroll header turn to frosted glass instead of opaque blocks.
- feat(workspace): A tidier titlebar at any zoom. The browser-style tabs draw at equal width under a continuous arch, and the window controls no longer overflow when the app is zoomed in.
- feat(workspace): Remote windows show the workspace name. A remote-desktop window's status bar now shows the connected workspace's name — with its address on hover — beside the session count.
- fix(search): The file search dialog finds deeply-nested files. A gitignore-aware backend walk reaches files at any depth without descending into node_modules or target, and fuzzy ranking surfaces deep matches. The composer's @-mention picker benefits too.
- fix(workspace): Cursor and Grok delegation cards show their icon again. They no longer render a blank icon for those sub-agent types.
