הורדת codeg 0.11.1

- feat(terminal): configurable default shell with backend-driven picker — get_available_terminal_shells / probe_terminal_shell_path serve the platform-aware option list, install state and resolve_shell() fallback; the settings UI renders the response verbatim and supports a custom shell path on every platform. POSIX spawn now distinguishes bash-family shells from unknown shells like nu/xonsh/elvish so the latter spawn cleanly without bash-only -l -i / eval flags. Localized across all 10 languages. Thanks to @Kwensiu for contributing the initial implementation in #127.
- feat(chat): file paths in Read/Write tool call headers and Edit/ApplyPatch diff headers are now clickable and open the file in the workspace panel via the existing local-file confirmation dialog; new-file Write/NotebookEdit bodies render with the same green tint as added diff lines.
- feat(chat): cap inline code block height inside messages with internal overflow scroll, so long code dumps no longer push the rest of the conversation off-screen.
- fix(dialog): constrain DialogContent to viewport height with internal scrolling, and cap the git reset commit message at 8rem with its own scrollbar, so the dialog footer stays visible on long messages or short viewports.
